摘要

应用完整形式的改进代数Reynolds应力模型对旋流燃烧室内两股同轴旋转射流的湍流流动进行了数值模拟 .模拟得到的结果与实验测量数据以及k -ε模型和简化形式的改进代数应力模型的模拟结果进行的对比表明

改进的代数应力模型可以给出比k -ε模型和简化形式的改进代数应力模型更为合理的湍流旋流流场模拟结果 .

Abstract

A full form of the improved algebraic Reynolds stress model(ASM)is employed to simulate swirling turbulent flows in a swirl combustor with two coaxial jets in this paper.The calculated results are compared with the measured test data and those predicted by the k-ε model and a simplified form of the improved ASM.It is shows that better predictions are achieved by the full form of the improved ASM

which are closer to the measured data than those obtained by the other two models.
