The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

Abstract

We use direct numerical simulation to study the mixing behaviour of pulsed jets in crossflow. The pulse is a square wave and the simulations consider several jet velocity ratios and pulse conditions. Our objective is to study the effects of pulsing and to explain the wide range of optimal pulsing conditions found in experimental studies of the problem. The central theme is that pulsing generate...

In this study, the performance of a novel method where an antibacterial solution is pressurized and sprayed into recirculated air through nozzles, investigated numerically. This resembles jet in crossflow problem mixes with ventilation further adheres to inner surfaces duct. The motion particles dispersed described as advection passive scalar, i. e., temperature, allowing for single-phase flow ...
