In Formula Society of Automotive Engineers (FSAE) cars engine heat management serves as an important factor for the performance of the vehicle. Therefore, a proper design of sidepod is crucial for optimal cooling of the engine since sidepods are designed to direct the airflow through the radiator. Also, since sidepods play an important role in the aerodynamic performance of the vehicle, factors such as drag and lift must also be considered along with the cooling of the engine. This paper brings forth the methodology carried out to design the sidepods effectively. First the optimal radiator angle is determined on which the maximum mass flow rate of air through the radiator core is observed. Angles are varied from 50, 70 and 90 degrees on various orientations with respect to the car. Fixing this radiator angle, various inlet and outlet areas of the sidepod are analyzed. Choosing the model with least drag and lift coefficient the sidepod is analyzed by sealing it at various sides. Finally, the effects of gills are also analyzed for better optimization of the sidepod. The models are designed in Solidworks and the CFD simulations are carried out in Simscale. Half car simulation is performed with symmetry conditions in order to reduce the cell count. The results of the analysis showed that the radiator angled forward with a diverging type sidepod yields in the better cooling of the engine.

Predict accurately resistance of the ship and flow around ship hull form is extremely important as these are input parameters for optimizing ship hull form, designing the ship propulsion system. This paper focuses on the numerical simulation of the flow around the Container Ship Fortune Freighter in calm water condition at different ship speeds by using CFD method. The results of impact of ship speed on components of ship resistance, wave patterns, volume fraction of air, the distribution of pressure, and wall shear stress on the ship's hull surface, as well as the nominal wake field are provided and analysed in this paper.

This study is aimed to develop a simulation to improve the performance of the finned tube evaporator which is applied to the refrigerated display cabinet. CFD model was developed to be able to analyse the characteristics of air flow inside the fin gap and air side heat transfer coefficient. Geometry of the model of overall finned tube evaporator is considered covering two aluminium wavy fins with an air flow in between, combination of staggered cooper tubes with refrigerant flow inside. Fin gap is designed 4 mm to anticipate frost on the fin surface that can block air flow. Turbulence models used in the study is the realizable k-ε turbulence which had the best performance turbulence model and it was validated with secondary data from previous studies and shows the lowest error only 5.9 %. The use of CFD was found to be sufficiently representative of the heat transfer characteristics of evaporators, and acted as an effective simulation tool to determine the heat transfer coefficient in order to improve efficiency in terms of improved design. The characteristics of air flow between the fin gap and around the tube was obtained various and complex. In the case study the entry velocity of 1.7 m /s at the highest turbulence condition of the first row can reach speeds of 2.75 m/s. Hight turbulence regime in flow can indicate higher the heat transfer coefficient of the evaporator.
