| Abstract: | Based on a small two-stroke air-cooled aero-engine,the heat transfer of cylinder for air-cooled engine was simulated according to the theory of the fluid-solid coupled heat transfer,in combination with characteristics of heat transfer and discipline of combustion.In this theory,the heat conduction between the cylinder and cylinder liner was considered as internal condition of the system,which can make the simulation simple and convenient;as compared with the experiment result;this shows that coupled analysi... |
