摘要
本文对一个侧壁受定热流作用的通风小室在两种气流组织型式下的混合对流换热情况进行了数值模拟 ,计算得到了流场 ,温度场及混合对流条件下室内的换热情况等随雷诺数Re和瑞利数Ra的变化规律。
Mixed convection heat transfer in a ventilated room subjected to a constant heat flux from the side wall is investigated numerically at two different air distribution modes.Through calculation,flow fields,temperature fields and mixed convection heat transfer rates are obtained for different values of Reynolds and Ra numbers.
