摘要
将湍流重整化群 ε方程与 Zhang Jian提出的新代数应力模型结合 ,用于模拟煤粉浓淡燃烧器喷口强旋转流场。通过对 7个工况流场的计算 ,并与实验结果比较 ,得出燃烧器喷口流场随参数变化的规律 。
WT5”BZ]This paper introduces an algebraic stress model with k and was ε equation based on the Renormalization Group theory.The present model (RNG ASM) was applied to simulate the swirling jet flow from a pulverized coal rich/lean burner.The aerodynamical property of the swirling jet flow from the burner was studied numerically in detail.The simulating results by the RNG ASM model are compared with the experimental data,and the comparison shows good agreement with each other.
