Thermal energy storage through phase change material has been used for wide applications in the field of air conditioning and refrigeration. The specific use of this thermal storage has been for energy storage during low demand and release of this energy during peak loads with potential to provide energy savings due to this. The principle of latent heat storage using phase change materials (PCMs) can be incorporated into a thermal storage system suitable for using deep freezers. The evaporator is covered with another box which has storage capacity or passage through phase change material. The results revealed that the performance is increased from 3.2 to 3.5 by using PCM.

The use of ion implantation as a surface treatment technology has been conquered by its applications to prevent wear and oxidation in metal alloys, even though some early works already pointed out that ion implantation could also be effective as a surface treatment for other materials, including polymers. Further research has shown that low dose implantation of energetic light ions could be very effective for improving properties such as wear resistance and hardness in many different polymers. Cross linking of polymeric chains due to ionization energy provided by the stopping process is the main mechanism to explain the changes in mechanical properties. According to this model the lighter the ion is, the stronger is the effect. This thesis presents the results obtained by nitrogen implantation in ultra-high molecular weight polyethylene (UHMWPE). N+ ions were implanted at 80 keV, 100 keV and 120 keV energy levels which are maintained at a fluencies or dose of 5×1015 ions/cm2 . Wear resistance was measured using pin-on-disc wear testing machine at a constant load of 18 kg or 177N with a sliding speed of 2 m/s for about 1000m sliding distance. The results clearly show a lower weight and volume loses for samples implanted with nitrogen, in comparison to those implanted with untreated samples. Hence from the results of weight and volume loses of the treated or implanted samples with nitrogen ion, gives very good wear resistance than untreated samples.

This paper describes the design and experimental analysis of composite leaf spring made of glass fibre reinforced polymer. The main aim is to compare the load-carrying capacity, stiffness and weight savings of composite leaf spring with that of steel leaf spring. The design constraints are stress and deflection. The dimensions of an existing conventional steel leaf spring of a light commercial vehicle were considered for the present work. A traditional composite multi-leaf spring was fabricated with the same dimensions using E- Glass/Epoxy unidirectional laminates. Static analysis of 2D model of conventional leaf spring has also been performed using ANSYS 10 and compared with experimental results. Finite element analysis with a full load on the 3-D model of composite multileaf spring was performed using ANSYS, and the analytical results were compared with experimental results

The effect of welding parameters (current, electrode diameter) on the impact of low carbon steel specimens was investigated in this work. Two different geometries namely square butt welded joint and double V welded joint were created. The welding operation was carried out at three different current for welding currents of 90, 110 and 130 amps and electrode diameters of 2.5, 3.2 and 4mm respectively. A Charpy impact testing machine was used to evaluate the impact of the welded samples. It was observed that a low current of 90 Amps for all the welding electrode diameters produced high impact values for both the welding geometries. Also, the 3.2 mm electrode diameter was found to be more suitable for welding the square butt and the double V geometry as it yielded higher impact values. Additionally, the double V geometry showed better performance when compared to the square butt geometry for all the combinations of welding currents and electrode diameters.

In this investigation an attempt has been made to study the effect of welding on fusion characteristics of pulsed current gas tungsten arc welded AZ31B magnesium alloy joints. Five joints were fabricated using different levels of welding speed (105 mm/min –145 mm/min). From this investigation, it is found that the joints fabricated using a welding speed of 135 mm/min yielded superior tensile properties compared to other joints. The formation of finer grains and higher hardness in fusion zone and uniformly distributed precipitates are the main reasons for the higher tensile properties of these joints

The basic aim of a wind-operated bike is to ensure safe and eco-friendly drive. Here, the bike is run with the help of the battery. When we accelerate the throttle, the electric current from battery passes to controller. Then controller will sense the electric power according to the throttle position. It transmits the electric current to BLDC motor. E-bike battery has limitation that it runs only around 70 km and after that, the battery will be discharged. Therefore, the interesting thing about the windoperated bike is the battery will continuously charge with the help of the DC motor. The DC motor having 300 R.P.M. and it produces 14v and 0.40A by using of fan. The fan is directly attached to the DC motor, we get continuous power at specific speed of the bike, and battery will be charged continually. The wind-operated bike must be eco- friendly i.e. there should be no emission; there should be enough speed to travel, efficiency and comfort. Its body should be strong enough to withstand the road shocks or bumps. There should be less charging time for charging the vehicle whenever it is required.

The Thermal Power plant contributes major proportion of installed capability in global power generation system as well as in Indian power generation systems. Therefore, achieving an optimal operation for the same, by conducting parametric study and optimizing few parameters which has a noticeable effect on the power generation may prove beneficial for plant efficiency. The simulation has been the tool for optimal operation and control of different variables in power plant. In addition, it also provides hands on experience to the trainee so that, they can have a better exposure of control room. In this part of the study, for the analysis purpose the SIM simulator (Standard Power Plant simulator) is being used which is comprehensive, dynamic and has a multi-fuel running ability employed with tandem-compound steam turbine-generator which is designed to operate at 210 MW. Moreover, it is also characterized by disturbances and malfunction features along with monitoring provision, which assists in parametric study and generates results in form of graphical representation to predict the effect of parameter on performance of power plant. Currently three parameters are chosen for further study. The effect of blow down process, Air leakage in condenser and coal moisture are selected.

Additive Manufacturing (AM) opens new opportunities for the economy and the society and the global market of this technology is growing rapidly. However, quality assurance remains the main barrier for a broader integration of AM in the industrial sector. Most quality-related problems of AM are caused by uncontrolled variations in the production chain. By identifying the key controlling parameters or the Key Characteristics (KC) and introducing the proper process control protocol for these parameters, the effect of these variations can be limited and expensive monitoring, rework, repair and quality-related problems can often be avoided. The work presented in this paper reviews the recent literature related to sustainability in AM and proposes a new approach into how the key characteristics, which are normally used to reduce variations in production, can give an insight to a sustainable AM.

The present paper describes an experimental study on influence of process parameters on dross properties in laser machining of AISI 304 material. Process parameters namely laser power, cutting speed and gas pressure are considered in the present work. Design of experiments is done using response surface methodology and analysis of variance is performed in order to identify significance and influence of process parameters on dross height. It is found that laser power and gas pressure are most significant parameters followed by cutting speed. Dross height increases with increase in laser power and decreases with decrease in gas pressure. On the basis of experimental analysis, a second order mathematical model is developed to predict dross height. Model predictions and experimental results are found in reasonable agreement. Further, optimization of process parameters is also performed to minimize dross height
