微尺度燃烧过程中传热准则数分析
Analysis of Criterion Number of Heat Transfer in Micro Combustion Process
摘要
Abstract
In the micro-scale conditions, due to the heat transfer coupling with the combustion process within the micro-combustor, the convection and heat transfer in the micro-combustor were rather complicated issues. Based on the simulation results of the flow, heat transfer and combustion process in the micro-combustor. Dimensionless analysis method was used to calculate the dimensionless Nux number which described the convection and heat transfer intensity in the channel cross-section away from the entrance at x. Then effects of inlet parameters on the dimensionless Nux number were analyzed. The formula between the dimensionless variables 0 and average Nux ,Rex ,Prx numbers in the channel cross-section was obtained by multiple regression analysis.关键词
