| 摘 要： | 提出了一种活塞燃气侧换热边界修正方法。在传统经验公式基础上，该方法基于能量守恒定律修正活塞燃气侧换热边界，并以某柴油机活塞为例进行了验证。结果表明:该方法计算的活塞燃气侧换热边界比传统公式法精确，比三维燃烧过程仿真分析获得换热边界的方法高效，适用于柴油机设计阶段活塞温度场快速评估。

| Abstract: | A modification method for boundary heat transfer of piston gas side is proposed. Based on the traditional empirical formula method, the improved method is made following energy conservation law to modify the heat transfer of piston gas side. And a piston of a diesel engine was taken as an example for verification. The results indicated that the method could determine the heat transfer boundary condition of piston gas side more accurate than traditional empirical formula method, and more effective than 3D combustion process simulation method, thus is applicable to rapid evaluation of piston thermal field in the design of diesel engines. |

| Keywords: | piston gas side heat transfer boundary condition thermal field |
