The Line Heating Temperature Field Theory Analysis and Numerical Simulation

Abstract

This paper analyzed the endothermic efficiency of the plate in line heating process combing with the need of researching on the recovery of waste heat in the gas flame process. Firstly the non-linear partial differential equations of three-dimensional transient temperature field were derived with the analysis of hexahedron in the plate. Then the temperature field of the plate was numerically simulated using gaussian heat source heat flux model with ANSYS software. Finally the heat absorption efficiency formula of the plate was derived based on the finite volume method. The endothermic efficiency model in this paper provides a basis for further analysis of the whereabouts of the heat released in line heating process in theory.
