Comparative Study of Analytical Method for Calculating Quartz Lamp Radiation Heat Flux under Multi-element Condition
摘要
Abstract
Radiation heat flux distribution of the quart lamp array is the direct way to assess rationality of heating design in thermal strength tests.An analytical computation method was present for the heat flux of the quartz lamp under multi-elements mesh for the semi-cylinder of the filament.The effect of different number of elements on the distribution of heat flux was discussed.In comparison with calculated results using finite element software,the main reason for the difference between the calculated results using analytical method and finite element method was the difference of total radiation energy of the filament.Then the adjusting method of temperature of the filament in the finite element model was built,which obviously improved the consistency between the calculated results.So the validity of the analytical computation method was verified,which could effectively reduce the scale of radiation heat transfer and get temperature response rapidly of the structure in large scale under the radiation heat transfer with large scale array of the quartz lamps if heat flux computed from this method was used as load in the finite element analysis.关键词
