摘要：
For the problem that semi-empirical formula is not suitable for the heat transfer boundary condition of high power density internal combustion engine, the revised semi-empirical formula for heat transfer in this model was proposed based on the WOSCHNI formula and the numerical calculation method of fluid-solid coupling. Taking a single cylinder test machine as an example, a three-dimensional steady-state coupled simulation system of head-sleeve was established. The numerical model was solved using Fluent software, and the results were compared with temperature test results of the whole engine. The results show that the relative error between simulation and experiment results is less than 5% under four conditions at power characteristics curve of high power density prototype. Therefore, the semi-empirical formula proposed and the fluid-solid coupling model established in this paper can well simulate the steady-state heat transfer of internal combustion engine. © 2018, Central South University Press.
