CFD Study of Heat Transfer and Pressure Drop Characteristics in Vehicle Radiators
In this study, the effect of vehicle speed into the radiators heat transfer and pressure drop characteristics were
numerically investigated using ANSYS-Fluent. In analysis, four different vehicle speeds (30, 60, 90, 120 km/h) were used
while the rest of the boundary conditions are kept constant. Both coolant and air flows were considered as turbulent, steady,
incompressible. Standard k-e model was selected as turbulance model. For each vehicle speed, the outlet temperature of the
coolant, cooling capacity of the radiator, radiator effectiveness and air side pressure drops were obtained. Apart from these,
temperature distributions for each vehicle speed were presented.
