中文摘要:在微尺度条件下,由于对流传热和燃烧过程耦合发生在很小的范围内,因此微燃烧室内部的对流换热问题比较复杂。根据微燃烧室内部流动、传热和燃烧过程模拟计算的结果,采用无量纲分析方法,计算出表征距入口x处各通道截面平均对流换热强度的努塞尔数Nux,并分析入口参数对Nux的影响。对多组计算结果进行多元回归拟合,最终得到各截面平均Nux与雷诺数Rex、普朗特数Prx和无量纲变量θ之间的函数表达式。

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 θ and average Nux,Rex,Prx numbers in the channel cross section was obtained by multiple regression analysis.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
