摘要

在传统的k-ε湍流模型基础上

在近壁区放弃求解ε方程而代之以根据共振三波理论模型在近壁区系统计算的ε值构成封闭

通过对NACA0012二维翼形流场的计算

初步验证并适当修正了新的理论模型

由于注意到了理论模型计算结果的无量纲性

从而改善了该流场的计算结果

得到了与实验更为相符的Cp分布。本文的分析还表明

逆压力梯度对ε的影响非常显著

验证了理论分析和计算得到的结论。

Abstract

Based on the classic k-ε turbulence model

ε equation is replaced by a theoretical model which formed a near-wall turbulence model.The calculation of the 2-D NACA0012 airfoil in low Reynolds number flow field validated the theoretical model.The non-dimensional property of the result obtained from the theoretical model improves the calculation

so the distribution of C_pagrees better with experimentation.The analysis shows that the effect of converse pressure gradient on ε is prominent

and it validates the result of theoretical and numerical computation.
