【摘要】 研究了两种不同外界来流方向的开口方腔内的混合对流换热问题。对不同的格拉晓夫数、R e以及纵横比进行了数值模拟。计算结果表明了与它们相对应的不同流型及换热效果,同时表明通过增加流速可以减小方腔与周围环境的热量交换。更多还原

【Abstract】 Mixed convection heat transfer in open-ended enclosures was studied numerically for two different inlet angles of attack.Different Grashof number,Reynolds number and the aspect ration were experimented numerically in the present study.The results show that the heat exchange are different when the flow patterns are different.the heat transfer from the cavity to the atmosphere can be decreased by increasing the velocity.更多还原
