Abstract

Method of virtual prototyping with the following mathematical modeling was used to simulate the heat-mass exchange and combustion during the operation of high-temperature gas infrared radiators, and to find optimal technical solutions for its design. The most authoritative and approved software product Ansys Multiphysics was used. The results of the mathematical modeling of heat and mass transfer in a turbulent reaction medium with combustion reproduce the experimental data produced by a measurement in real operating conditions of the gas-fired infrared heat emitter. The temperature distribution along the height of the ceramic nozzle was established. Obtained results enable estimation of the ignition and combustion zones.

Highlights

Two acute tasks of energy resources saving and energy efficiency increasing can be achieved by replacing convective heating systems of production buildings, warehouses, large pavilions, hangars with radiant heating systems based on high-temperature gas infrared radiators [1, 2]
Full virtual prototype of high-temperature gas infrared burner was built based on its sketches and complete geometric model (Fig. 1)
The construction of the computational grid is performed by ANSYS Workbench, namely, the volume is divided into finite elements - tetrahedrons in the amount of 3∙106

Introduction

Two acute tasks of energy resources saving and energy efficiency increasing can be achieved by replacing convective heating systems of production buildings, warehouses, large pavilions, hangars with radiant heating systems based on high-temperature gas infrared radiators [1, 2]. The method of virtual prototyping with the following mathematical modeling was used to simulate the heat-mass exchange and combustion during the operation of hightemperature gas infrared radiators, and to find optimal technical solutions for its design. Full virtual prototype of high-temperature gas infrared burner was built based on its sketches and complete geometric model (Fig. 1).
