布朗斯威克工科大学内然机研究所在一台高速、外源增压的MTU柴油机上对热传导进行了系统的研究。应用了确定工质和气缸壁之间传热系数的常规方法:如热平衡计算,温度场计算和瞬时变化的表面温度的测量。从而证明了作者建议的求解局部传热系数的方程,计算了工作过程中工质传给气缸壁的总热量,而且也正确地给出了活塞、缸套和缸套上热流的局部分布以及热流密度的瞬时变化。本文报道试验研究的第一批结果。
The internal combustion engine at the Brownswick Engineering University conducted a systematic study of heat transfer on a high-speed, externally pressurized MTU diesel engine. Conventional methods of determining the heat transfer coefficient between working fluid and cylinder walls have been applied: thermal equilibrium calculations, temperature field calculations, and instantaneous surface temperature measurements. It is proved that the author proposed an equation to solve the local heat transfer coefficient and calculated the total heat transferred to the cylinder wall during the working process. The correct distribution of the heat flow on the piston, cylinder liner and cylinder liner as well as the heat flow Instantaneous changes in density. This article reports the first results of a pilot study.
