Convective Heat Transfer From Two Rotating Circular Cylinders in Tandem Arrangement Using Lattice Boltzmann Method
用格子Boltzmann方法,数值研究流过前后排列两旋转圆柱体的二维层流.用二阶精度的速度场和温度场,数值化涉及运动的曲线边界.在Reynolds数为100,Prandtl数为0.71时,研究旋转速度比的变化和不同间距的影响.在4种不同间距(3,1.5,0.7,0.2)下,研究旋转速度比的不同范围.结果表明,当间距取大数值时,第1个圆柱体的升力和阻力系数,与单个圆柱体相类似；对所有间距(除间距3以外),第2个圆柱体的升力系数,随着角速度的增加而减…查看全部>>
A numerical investigation of the two-dimensional laminar flow past two rotating circular cylinders in tandem arrangement using lattice Boltzmann method was conducted. The numerical strategy for dealing with curved and moving boundaries of second-order accuracy for velocity and temperature fields was used. The effects of variation of rotational speed ratio and different gap spacing were studied at Reynolds number of 100 and Prandtl number of 0. 71. A various …查看全部>>
