摘要:
采用格子Boltzmann方法对二维封闭方腔自然对流换热进行研究. 通过数值模拟得到在不同Ra数和倾斜角θ,封闭方腔内的流场温度场的变化情况. 再根据流场温度场分析Ra倾斜角θ对封闭方腔自然对流换热的影响. 结果表明,Ra数的增大会增强自然对流换热,而倾斜角的增加使得自然对流换热增减交替,当倾斜角为90°时,自然对流换热最弱.
Abstract:
Using the Lattice Boltzmann method,we study the natural convection heat transfer in a two-dimensional closed square cavity. Numerical simulation is carried out to obtain the situation of the flow field and temperature field in the closed square cavity under different Rayleigh numbers and inclined angles. According to the flow field and temperature field,the influences of Rayleigh numbers and inclined angles on the natural convection heat transfer in the closed square cavity are analyzed. The results show that the increase of Rayleigh numbers enhanced the natural convection heat transfer,while the increase of the inclined angles leads the natural convection heat transfer to increase or decrease. At the same time,when the inclined angle is 90°,the natural convection heat transfer is the weakest.
