摘要
应用FLUENT软件,采用隐式有限体积法求解雷诺时均N-S方程,对几种不同扰流柱形状的层板冷却结构的内部流动进行了数值模拟。湍流模型采用Realizable k-ε双方程模型,近壁面采用壁面函数法处理,利用SIMPLE算法求解速度与压力的耦合。计算结果表明,层板内部流场结构十分复杂。同时,还对几种不同扰流柱形状的层板进行了流阻试验,采用沿程阻力关系式及流量关系式得出了其流阻特性。试验结果与计算得出的流阻特性符合较好。
Using an implicit finite volume method to solve the Navier-Stokes equation,numerical simulation was conducted to study internal flow field of several pin-fin configurations of laminate plates by employing FLUENT software.Turbulence model was Realizable k-ε double equation model.Standard wall function was used for near-wall treatment.The coupling of velocity and pressure were performed using the SIMPLE algorithm.The results indicated that the flowfields of laminate plates are very complex.The internal flow resistances of several pin-fin configurations of laminate plates were tested.The numerical results were in good agreement with the experiment data.
