涡流室柴油机瞬时传热率和瞬时传热系数研究

Study on Transient Heat Transfer Rate and Coefficient of Swirl Chamber Diesel Engine

在试验和计算的基础上，提出用瞬时燃气速度替代活塞平均速度计算瞬时传热率和瞬时传热系数，从而提高了精确度．

Based on experiments and calculations, the authors presents a method in which the transient heat transfer rate and coefficient are calculated with the transient gas velocity instead of the mean piston velocity, thus improv-ing accuracy of computation.
