摘　　要：In this study,laminar convective heat transfer over two heated wall-mounted cubes is investigated.Two cubes,which are under constant heat flux,are placed in different tandem and staggered arrangements on a base plate.This problem is studied for different streamwise and spanwise distances between two cubes in different Renolds number(Re),by using finite-volume method.Effects of these parameters are considered on flow and heat transfer characteristics.The results show that the temperature distribution is strongly dependent on flow structure and varies with any change of flow pattern in different arrangements of cubes.In addition,it is observed that the drag coefficient,which is influenced more by pressure forces,in staggered arrangement,is greater than tandem arrangement.Results show that by increasing the spanwise distance the amount of mean Nusselt number(Nu)of Cube 2 becomes the same as Cube 1. 关键词：立方体热转移脚踏车对流使用参数流动模式流动结构热流动
