Numerical simulation of flow in modern jet nozzle diffuser
Incoming article date: 30.05.2018Numerical simulation is becoming more and more widespread when solving the problems of air distribution and inflow air rate. One of the questions of using CFD approaches legitimacy is the possibility of a reliable description of the flow in modern air distribution devices. In the present work, physical and numerical experiments were carried out for the SMK 200 jet nozzle diffuser. Velocity profiles were taken at various distances from the jet nozzle during the physical experiment. Numerical investigation tool was the integrated package STAR-CCM +. Numerical simulation was carried out using various turbulence models. Simulation results showed that the use of the k-ɛ models allows to describe the parameters of the flow with sufficient accuracy. Number of cells required for the correct flow description in modern air distribution device is suitable for practical application.
