摘要
本文建立了内燃机气缸壁面传热过程的数学模型,传热系数采用欧洲广泛使用的Woschni、Woschni-Huber、Hohenberg和Bargende提出的经验公式计算。通过MOSES-Ⅱ内燃机工作过程数值模拟计算程序进行数值模拟。
This paper establishes a maths model of heat transfer process in cylinder wall of I.C. engines.Heat transfer coefficient is calculated with the experiential equations put forward by Woschni,Woschni-Huber,Hohenberg,and Bargende,which are extensively adopted in Europe.The numerical simulation is conducted via numerical simulation calculating program for I.C.engine operating process and the calculted results are compared with that of tests.
