Abstract

A numerical simulation is conducted to study the flow of a three-dimensional incompressible wall jet. The study aims to determine the jet structure and to compare the propagation mechanisms of turbulent and laminar wall jets. The numerical solution of the Navier–Stokes equations in the turbulent case is obtained using the wall-resolved large eddy simulation. The simulation results are compared to experimental data.

三维湍流壁射流的流动结构

摘要

通过数值模拟研究三维不可压缩壁射流的流动。该研究旨在确定射流结构并比较湍流和层流壁射流的传播机制。湍流情况下纳维-斯托克斯方程的数值解是通过壁分辨大涡模拟获得的。将模拟结果与实验数据进行比较。
