摘要
电子元件和系统的准确热预测变得越来越重要。在这里，基于RANS (Reynolds average Navier-Stokes)和LES (Large Eddy Simulation)方程的混合CFD方法应用于两种钝壁几何形状，以研究做出准确热预测的潜力。这些模型起源于航空航天工业，当应用于这些相对较低雷诺数的流动时，它们与实验数据和彼此之间的一致性很好。
Unsteady CFD modelling of turbulent flows for electronics
Accurate thermal prediction of electronics components and systems is becoming ever more important. Here, hybrid CFD methods based on the RANS (Reynolds Averaged Navier-Stokes) and LES (Large Eddy Simulation) equations are applied to two bluff geometries to investigate the potential to make accurate thermal predictions. Originating from the aerospace industry, these models, when applied to these relatively low Reynolds number flows, agree well with experimental data and each other.
