Coupled Simulation of Radiation-Convection-Conduction Heat Transfer for Honeycomb Receiving Concentrated Irradiation with Various Converging Angles

Abstract

This study investigates conjugate heat transfer problem for honeycomb structure under concentrated irradiation. This simulation model focuses on a unit rectangular channel made by stainless steel. The problem assumes the condition that the honeycomb structure is installed in vertical orientation and heated up by beam-down concentrated irradiation, and simultaneously air flows through honeycomb channel. Discrete Ordinates radiation model calculates discretized radiative transfer equation and solves mutually interaction of radiation, convection, and conduction. For investigating the heat transfer phenomena, the beam width, power on aperture, and air mass flow rate are changed.
