Phase 1 of Tuanku Jaafar Power Station, Port Dickson (PD1) is one of the newest power plants in Tenaga Nasional Berhad (TNB). This combined cycle plant with the nominal capacity of 750MW started its commercial operation in 2005. However, in less than 2 years of its operation, the plant has indicated significant capacity degradation. Consequently, TNB carried few investigations to determine the cause for the capacity degradation. This paper describes the approach taken and the outcomes of the investigations.

The PU/PIR duct has texture of 0.5mm height along the duct. This study focus on the frictional loss of flow through a rectangular duct of PU/PIR duct. As a compariosn a steel duct with surface roughness is also simulated. The duct considered in this study has a cross-section of 300mm × 300mm and length of 1500mm. The two designs are simulated in FLUENT proprietry software. The Hybrid tetrahedral element grids are used in building non-uniform mesh. The total computational nodes involved in the calculation are about 3 million cells. This is due to the small geometry of the PU/PIR duct texture at the wall. The appropriate boundary setting and numerical setting is explained in proceeding section. The geometry generated is then simulated for 200CFM, 400CFM, 800CFM, and 1200CFM flow conditions. (CFM = cubic feet per minute) The mesh generated and the results are presented. The coefficient of friction is calculated from CFD and plotted. The velocity and pressure distribution are also illustrated for all CFM simulated.

This paper describes the experimental procedure to evaluate the performance of short duration high speed flow shock tunnel located at the Universiti Tenaga Nasional “UNITEN”. The experimental work includes measurements of pressure, peak pressure, shock strength and shock speed. Physical description of the facility along with the principle of operation is presented. The pressure history of flow process was captured using fast response pressure transducer mounted at three stations located at the end of the facility. The measurements were performed using two different driver/driven gas combination. The first one is Air-Air while the second one was Helium-Air. The results of two combinations were compared and analyzed. The results show that the facility's performance is highly influenced the gas combination. The results provide very good estimate for the above mentioned parameters obtained after diaphragm rupture and also provide better understanding of the parameters that affect the performance of the facility.

This paper provides a brief insight into the advantages of utilizing nanofluids (nano-sized particles in fluid) in replacement of conventional coolant materials. Nanofluids have been recognized as an alternative coolant material due to the heat transfer enhancement thus reducing the required coolant power. This paper presents numerical simulations of convective heat transfer under laminar flow conditions. The parametric study has been carried out and the results are presented for both heat transfer coefficient and wall shear stress with the introduction of titanium-oxide (TiO2) nanoparticle of volume fraction 0% to 10% into a solution of pure water. The study also presents the results to show the effect of increasing nanoparticle volume fraction on wall shear stress. It is found that both the heat transfer coefficient and the wall shear stress increases with the increase of the volume fraction of nanoparticles.

This paper describes the application of the built-in Volume-of-Fluid (VOF) model in the commercial Computational Fluid Dynamics (CFD) software FLUENTTM and the verification of its accuracy. As the VOF model is based on the field volume fraction calculations and surface reconstruction methods, in which a free surface is not explicitly tracked, the aim was to verify that a reconstructed surface obtained by VOF simulation is representative of a real surface. For this purpose, various cases of a thin liquid film flowing into rectangular cavities were simulated and the resulting surface profiles analyzed in terms of the normal velocity of the constructed surface, which should be zero in a real surface. Both the cases of small and large surface tension coefficients were simulated and the results showed that the VOF model is capable of generating surface profiles with reasonably accurate normal velocity condition for the cases with small or no surface tension. For high surface tension values, the existence of spurious interface velocity as previously reported in the literature was confirmed. Comparisons of the VOF-calculated surface profiles with the ones obtained using the explicit surface tracking algorithms such as the Boundary Element Method (BEM) reported in the literature showed that the VOF model is able to produce the expected profiles of thin liquid film flowing a two-dimensional rectangular cavity and thus can be considered for simulation of other applications involving thin liquid film flows, provided the grid refinement based on the volume fraction gradient is applied.

Elements of a discrete particle model that might find application in aircraft engine icing studies are introduced in this paper. As it currently stands, the model is in an embryonic state but it does provides a framework from which further developments can easily proceed. It provides a convenient basis for assessment of aerodynamic particle drag, surface friction, heat transfer and other effects likely to be relevant in the engine icing problem. The model treats the initial stage of accretion, before the inviscid stagnation point flow field is measurably affected by the presence of the ice build-up. The intention is to provide an indication flow field and surface conditions that are likely to lead to stable accretion of ice prior to detectable changes in the aerodynamics of the stagnation point flow field. Preliminary results from the model are presented to demonstrate the current functionality of the model.

In natural seawater, pure aluminum develops oxide layer which forms a barrier, protecting against corrosion. Alloying with other elements prevents the development of oxide layer by introducing localized galvanic cells. Different aluminum alloys exhibit different electrochemical behavior. The scope of the project was to study the effects of the addition of Zn, Sn, Mg, Cu, Fe, and Si on the morphology and corrosion behaviour in aluminium alloys. This is part of the work to study the electrochemical behaviour of aluminum alloys in natural seawater. The significance of understanding the corrosion behavior of aluminum alloys is essential in the fabrication of sacrificial anodes to be used in cathodic protection in corrosion control. Aluminum alloys were fabricated using alloying elements Zn, Sn, Mg, Cu, Fe, and Si. Divided into two groups, samples of aluminum alloys in Group 1 contain same weight percent of Zn, and different weight percent of Sn. Aluminum alloy samples in Group 2 contains same weight percent of Mg, Cu, Fe and Si with different weight percent of Sn. It was observed that the activeness of aluminum alloys also increases when alloyed with Zn, Sn, Mg, Cu, Fe, and Si.

In former times, engineers were only concern about “designing” a product that meets its objectives. Little concern was given to the future availability of natural resources. Current design trends are more stringent to say. Not only the product has to fulfill its objectives/ functional performance, but it has to fulfill the market needs and at the same time ensuring there is minimal material or energy wastage. The objective of this study was to address the later requirement which is minimizing material wastage. The study focused on size optimization of the frontal vehicle structure via design of experiment and finite element analysis. The outcome of the study was encouraging. A weight savings of 8 kg was achieved without severely affecting the crashworthiness behavior of the vehicle.

In the time of rapid growth, there is an increase of demand for a reliable and stable power supply. Power utilities are pressured to cater the rising demand with the existing system. Thus, monitoring the voltage stability of the system has become crucial. Under Voltage Load Shedding (UVLS) is one of the many methods that are used to sustain voltage stability. On the other hand, Fast Voltage Stability Index (FVSI) index is proven to be a good indicator for voltage stability in a system. This paper will study on the correlation between FVSI index and UVLS scheme. From the simulation, the results clearly indicate that FVSI index can be used to indentify location to be load shed.
