Abstract

Numerical simulation is applied to investigate the outflow of an incompressible three-dimensional turbulent swirled wall jet. The purpose of the study is to determine the jet flow structure and to compare the characteristics of swirled and nonswirled jets. The numerical solution of the equations of motion is obtained using large eddy simulation with wall resolution (WRLES). The results of the modeling are compared with the data of a unique published study devoted to experimental investigation of swirled wall jets.

湍流漩涡壁式喷流

摘要应用数值模拟研究了不可压缩三维湍流漩涡壁射流的流出情况。研究的目的是确定射流的流动结构，并比较漩涡射流和非漩涡射流的特征。运动方程的数值解是通过带壁分辨率的大涡模拟（WRLES）获得的。建模结果与已发表的专门用于漩涡壁面喷流实验研究的数据进行了比较。
