摘要

基于Launder-Sharma(LS)低雷诺数k-ε两方程湍流模型发展了一种改进的具有转捩敏感性的低雷诺数湍流模型.针对LS模型的可实现性(realizability)问题和前缘滞止点湍动能预测过大的不足

模型进行了改进.改进模型只使用当地物理量

不需要求解壁面距离、y+和边界层积分参数.改进模型能够适用于广泛的流动

且容易应用到通用的计算流体动力学(CFD)程序中.对具有详细数据的零压力梯度平板转捩边界层T3A实验的模拟结果显示

改进模型能够预测转捩流动

并能对自由湍流变化给出合理的响应.

Abstract

The paper presented the initial development of an improved two-equation low-Reynolds-number(LRN) turbulence model with transition sensitivity

based on the Launder-Sharma(LS) turbulence model.Several modifications were made for LS model's disadvantage on realizablity and stagnation point anomaly.The improved model only uses local variables.No need of calculating wall distance

y+ and boundary layer integral parameters makes it can be used for a wide range of flows

and this feature also makes it more easily implemented into general-purpose computational fluid dynamics(CFD) codes.The numerical simulation results of T3A test

a zero pressure gradient transitional flat plate boundary layer flow experiment

with detailed experimental data shows that the improved model can predict transitional flow

including an appropriate response to freestream turbulence intensity variety.
