摘要

基于Reynolds平均Navier Stokes (RANS)方程和大涡模拟(LES)公式的混合方法进行了研究，试图提高电子系统和部件的传热和表面温度预测的准确性。采用混合ransles、ranss -隐式LES (ranss - iles)和非线性LES模型研究了两种相对低雷诺数的流动。即使使用不同的网格分辨率，使用这些方法的预测结果也非常一致。

Strategies for Modeling Turbulent Flows in Electronics

Hybrid methods based on the Reynolds Averaged Navier Stokes (RANS) equations and the Large Eddy Simulation (LES) formulation are investigated to try and improve the accuracy of heat transfer and surface temperature predictions for electronics systems and components. Two relatively low Reynolds number flows are studied using hybrid RANS-LES, RANS-Implicit-LES (RANS-ILES) and non-linear LES models. Predictions using these methods are in good agreement with each other, even using different grid resolutions.
