This study aims to develop a new energy certification rating system in hot and dry climates. To do this, sustainable strategies must be applied for tertiary buildings. The methodology consists to evaluate these passive strategies by covering three proportions of sustainability (energy, economic and comfort), with a dynamic simulation. In addition, to calculate energy performance and energy savings indicators, we are carrying out a survey to establish reasonable and fair criteria for case study. In this study, four stages were carried out data collection and analysis, evaluation of the energy performance indicators of the strategies. With a multi-criteria analysis, we can evaluate indices of the energy performance of a building, in order to set up a new energy certification, which can allow energy savings and maintain comfort.

The Urban Heat Island (UHI) effect occurs when the temperature of the asphalt pavement surface exceeds 70°C during the summer. Rutting is a significant temperature-related problem that occurs when the temperature rises too high on asphalt surfaces. Additionally, this phenomenon increases the amount of energy required to cool buildings adjacent to pavements and degrades air quality. The Asphalt Solar Collector (ASC) was examined in this work by inserting tubes into the pavement's construction and circulating working fluid within it to capture thermal energy generated by asphalt pavement. A low-carbon steel-alloy cheap waste materials have been investigated as an extended surface with HMA. The effect of various extended surfaces attached to the embedded tubes on the thermal performance of ASC has been studied to determine whether it satisfies specified aforementioned demands. The performance of several ASC models with bare, continuous finned, and mesh grid serpentine embedded tubes was investigated with same Conductive Hot Mixture Asphalt (C-HMA) by using a numerical 3-D model developed by COMSOL Multiphysics Software. when the Reynolds Number is increased, it is found that ASC efficiency increases from 66.74% for bare serpentine tubes to approximately 75.488% and 69.4% for continuous finned and mesh grid serpentine embedded tubes, respectively. A maximum value of about 398.53 W can be gained (from a total of 850 W/m2 incident solar radiation) by utilizing an extended surface. Additionally, the surface temperature of HMA decreases significantly from 52.67 to 46.07℃. For all models under investigation, it is clear that the optimum average Reynolds Number is about 600. It is found that the continuous fins model can capture more solar radiation than the mesh grid model by about 8.77%.
当夏季沥青路面表面温度超过70℃时,就会产生城市热岛效应。车辙是一个与温度有关的重要问题,当沥青表面温度升高过高时就会发生车辙。此外,这种现象增加了冷却靠近人行道的建筑物所需的能量,并降低了空气质量。沥青太阳能集热器(ASC)在这项工作中通过将管道插入到路面结构中并在其中循环工作流体来捕获沥青路面产生的热能。研究了低碳钢-合金廉价废料的HMA扩展表面。本文还研究了埋管上不同延伸表面对ASC热工性能的影响,以确定其是否满足上述要求。利用COMSOL Multiphysics软件开发的三维数值模型,研究了在相同导热热混合沥青(C-HMA)条件下,裸管、连续翅片管和网状网状蛇形埋管的几种ASC模型的性能。当雷诺数增加时,裸蛇形管的ASC效率从66.74%增加到连续翅片蛇形管的75.488%和网状网格蛇形管的69.4%左右。利用扩展表面可获得约398.53 W的最大值(从总850 W/m2入射太阳辐射中)。HMA表面温度从52.67℃显著降低到46.07℃。对于所研究的所有模型,很明显,最佳平均雷诺数约为600。结果表明,连续翅片模型比网格模型能多捕获约8.77%的太阳辐射。

Simulation Study of a Flat Plate Solar Collector Influence of the Mixture Air Flow 混合气流对平板太阳能集热器影响的模拟研究
Pub Date : 2021-12-31 DOI: 10.18280/psees.050103

Due to their simple composition, flat plate solar collectors are constantly applied to various fields. As a result, thermo-fluid performance is continuously improving. The direct heat losses in a flat plate solar collector depend essentially on the absorber-glazing clearance. The increase in this clearance leads to an increase in convective losses and its reduction reduces the air flow to be transported. A solution is envisaged by the present subject, which consists in carrying out a new design of an absorber for those with baffles or part of the heat transfer fluid circulating inside. The work consists in optimizing the annular clearance or in circulating the heat transfer fluid because this clearance is made to the detriment of the thickness of the absorber, source of thermal energy of the solar collector. The optimum distance is then sought, which ensures a homogeneous mixture between the current of the main fluid flowing between the baffles on the one hand and the current of the secondary fluid flows in the annular clearance of the absorber on the other hand.
由于其组成简单,平板太阳能集热器不断地应用于各个领域。因此,热流体性能不断提高。平板太阳能集热器的直接热损失主要取决于吸收体与玻璃的间隙。这个间隙的增加导致对流损失的增加,而它的减少减少了要输送的空气流量。本课题设想了一种解决办法,它包括为那些有挡板或部分传热流体在内部循环的吸收器进行一种新的设计。这项工作包括优化环空间隙或循环传热流体,因为这种间隙会损害吸收器的厚度,太阳能集热器的热能来源。然后寻求最佳距离,以确保在挡板之间流动的主流体的电流与在吸收器环形间隙中流动的二次流体的电流之间的均匀混合。

The physical phenomenon of thermodiffusion is the transfer mechanism that occurs when a thermal gradient is applied to a mixture. It is known as “the Soret |Effect”, of which much experimental and theoretical work has been done to interpret it scientifically. This article briefly presents a one-dimensional theoretical and numerical approach, based on the first law of thermodynamics, of the concentration distribution of the NaCl in a salinity-gradient solar pond. The theoretical developments aim to frame its fluido-thermodynamic factors.

In the GMAW process of selecting appropriate values for the input parameters necessary in order to achieve weld is high with appropriate geometry and penetration. Since the stress-bearing capacity of the weld geometry, weld quality and also has an important role in determining the mechanical properties of the weld. In this study, the effects of voltage, wire feed speed, distance nozzle to the work piece, welding speed and coating thickness of ZrO2 Nano particles is intended as input parameters. The first, for coating Nano particles with specific dimensions on the surface of parts to be coated welding operation. After welding the weld penetration depth was evaluated. increasing the depth of penetration of the active coating on the surface (Nano zirconium oxide), which place the mechanisms leading to increased focus and arc current density at the top of the arc. Marangoni has also changed from negative to positive flow direction, the depth of penetration is increased. The results showed that fixed taking into account the input parameters and increase the coverage of ZrO2 Nano-particles on the surface to thickness 0.75 mm, weld penetration depth compared to non-Nano scale zirconium oxide coating has been increased. in addition to the effect of ZrO2 nanoparticles as a coating surface-active and increase the depth of penetration, such particles can cause tiny inclusions inside the structure weld, nucleation centers has been caused for the formation of acicular ferrite.
在本研究中,在GMAW工艺中,将ZrO2纳米颗粒用于St37板材上,以改善几何形状并增加焊深。在GMAW过程中选择适当的输入参数值是必要的,以达到焊缝高且具有适当的几何形状和焊透性。由于焊缝几何形状的承载能力、焊缝质量对焊缝的力学性能也有重要的决定作用。在本研究中,将电压、送丝速度、喷嘴到工件的距离、焊接速度和ZrO2纳米颗粒涂层厚度作为输入参数。首先,将具有特定尺寸的纳米颗粒涂覆在待涂焊件表面进行操作。焊接后对焊深进行了评价。增加表面活性涂层(纳米氧化锆)的渗透深度,从而在电弧顶部放置导致焦点和电弧电流密度增加的机制。马兰戈尼的流动方向也由负向正转变,穿透深度增加。结果表明,考虑输入参数的固定,增加ZrO2纳米颗粒在表面的覆盖厚度至0.75 mm,焊缝熔透深度较非纳米级氧化锆涂层有所提高。ZrO2纳米颗粒除了起到镀层表面活性和增加渗透深度的作用外,此类颗粒还能在焊缝内部造成微小的夹杂物组织,造成成核中心形成针状铁素体。

Among the renewable energy sources, photovoltaics seems to be the most promising source. It has the advantage of being available everywhere, friend of the environment and easily maintainable. Nevertheless, the major disadvantages are high manufacturing cost, low energy conversion efficiency and non-linear characteristics. On the other hand, the fuel cell is undoubtedly the least polluting means of making electrical energy. Indeed, apart from electricity, the reaction between hydrogen and air produces only water vapour. As such, the process does not reject any greenhouse gases, unlike the combustion of fossil fuels. Whether in a transport-type application (bus or car, or stationary, energy systems including PV or Fuel Cell systems have a in such systems, several levels of control are to be studied, modelled and optimized; this last point, according to one or more criteria of the whole system, can intervene at several levels: optimization of the topology as well as optimization of component sizing. This paper addresses the modelling of hybrid PV-PEM fuel cell power system where the whole system components are implemented using Matlab/Simulink environment. The main parts (PV and PEM fuel cell) are analyzed and investigated alone and in hybrid mode using different scenarios tests. The simulation results show the advantages of using such hybrid system in providing electrical energy in different use cases.
在可再生能源中,光伏似乎是最有前途的来源。它的优点是随处可用,对环境无害,易于维护。然而,主要缺点是制造成本高,能量转换效率低,非线性特性。另一方面,燃料电池无疑是制造电能的污染最少的手段。事实上,除了电,氢和空气之间的反应只产生水蒸气。因此,与燃烧化石燃料不同,该过程不排斥任何温室气体。无论是在运输类型的应用(公共汽车或汽车,或固定,能源系统,包括光伏或燃料电池系统有一个在这样的系统,几个层次的控制是研究,建模和优化;最后一点,根据整个系统的一个或多个标准,可以在几个级别进行干预:拓扑的优化以及组件大小的优化。本文对混合动力PV-PEM燃料电池动力系统进行了建模,并在Matlab/Simulink环境下实现了系统的各个组成部分。主要部件(PV和PEM燃料电池)分别在单独和混合模式下进行了分析和研究。仿真结果表明该混合系统在不同用例下提供电能的优势。

This paper represents the characterization process of mono-facial solar cell in Bangladesh Atomic Energy Commission (BAEC) Lab. Mono-facial solar cell characterization performance analysis using surface reflection method, Sheet resistance method, SEM, Surface photo voltage and LIV test. The morphology of silicon wafer surface has been studied using scanning electron microscopy. It is found that the pyramid type structures are formed on the textured surface which helps to trap more light during conversion to electricity. The sheet resistance of raw and diffused sample is measured by using four point probe method. Results show that the resistivity of the wafer is decreased after diffusion which indicates the formation of n-type layer during diffusion process. The surface photo voltage data is used to find the diffusion length and life time. It is found the diffusion length 81.5μm and life time is 2.5μs. Finally, the efficiency of monofacial solar cell measured by LIV tester. Results show that the monofacial solar cell achieved fill factor (FF) of 0.310423 with a conversion efficiency (η) of 5.193843% where the active surface area is 96 cm2.
本文介绍了孟加拉国原子能委员会(BAEC)实验室单面太阳能电池的表征过程。利用表面反射法、薄片电阻法、扫描电镜、表面光电电压和LIV测试对单面太阳能电池进行性能表征分析。用扫描电子显微镜研究了硅片表面的形貌。研究发现,在纹理表面形成的金字塔型结构有助于在转换为电时捕获更多的光。采用四点探针法测量了原始样品和扩散样品的薄片电阻。结果表明,扩散后晶圆的电阻率降低,表明扩散过程中形成了n型层。利用表面光电压数据计算扩散长度和寿命。扩散长度为81.5μm,寿命为2.5μs。最后,用LIV测试仪测量了单面太阳能电池的效率。结果表明,在活性表面积为96 cm2时,单面太阳能电池的填充系数(FF)为0.310423,转换效率(η)为5.193843%。
