A 3D numerical simulation model of periodic heat-transfer channel of louver fin which was used in the automobile ribbon-tubular radiator was established in this paper. The evolution of the heat convection feature and the influence to the inlet and outlet pressure losses were analysed when the velocity of the inlet airflow increases. The distribution character change function along the axial line of...
Numerical simulation of two-dimensional stagnation-point flow is investigated with the computational fluid dynamics (CFD) software of STAR-CD and results are compared with those obtained from the similarity solution. Study shows that velocity profiles are in good agreement between numerical simulation and similarity solution for high aspect ratio in the stagnation-point region. Numerical simulation...
Microscale ionic wind is a method of generating local boundary layer distortion to enhance convective heat transfer. An extension of the microscale ion driven airflow (MIDAF) concept, microscale ionic wind exerts a body force on an existing bulk flow through the phenomenon of ion drag. Ion drag results from repeated collisions between positive or negative ions with neutral air molecules. The ion-induced...
