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.

具有气体红外发射器、空气交换系统和工作区局部围栏的房间内传热的数学模型

摘要

对带有气体红外发射器、空气交换系统、水平面板模拟设备和局部围栏的房间内的传热过程进行了数学建模。求解了辐射传热系统、能量和空气的 Navier-Stokes 方程以及固体元素的热方程。作为建模结果获得的温度和气流速度场说明了在其边界安装特殊围栏时控制局部工作区域热状态的可能性。已经确定，通过改变围栏高度和材料，可以改变当地工作区域的当地和平均气温。
