Mathematical Modeling of Heat Transfer in a Room with a Gas Infrared Emitter, an Air Exchange System, and a Local Fence of the Working Area

Abstract

Mathematical modeling of heat transfer processes in a room with a gas infrared emitter, an air exchange system, a horizontal panel simulating equipment, and a local fence has been carried out. The system of radiative heat transfer, energy, and Navier–Stokes equations for air and heat equations for solid elements was solved. The temperature and air velocity fields obtained as a result of modeling illustrate the possibility of controlling the thermal regime of the local working area when a special fence is installed at its boundary. It was established that by changing the fence height and material one can change the local and average air temperatures in the local working area. The results of numerical studies suggest that by varying the local fence parameters one can create more comfortable temperature conditions in the local working area when gas infrared emitters operate under sufficiently intense air exchange conditions.
