一种适用于柴油机结构温度场计算的缸内传热模型

摘要/Abstract

摘要：

摘要：基于量纲分析式h(,i)=C()d－0.2p0.8w0.8T－0.8μ－0.47eλ0.67ec0.33p分析了柴油机的缸内三维局部传热情况，其特征参数选取缸内瞬态流动传热参数，并通过Woschni模型计算传热总量，在每个曲轴转角条件下，保证局部传热计算中对全部壁面网格热流求和所得传热总量与Woschni模型的计算值相等，以确定待定系数C().同时，将改进的缸内传热模型应用于一款单缸水冷自然吸气式四冲程直喷柴油机的缸内传热计算，所得模拟结果与实验结果吻合.

Abstract:

Abstract： Based on the dimensional formula h(,i)=C()d－0.2p0.8w0.8T－0.8μ－0.47eλ0.67ec0.33p, a local heat transfer model was developed and characteristic parameters were proposed as transient flow and heat transfer parameters. The total quantity of heat transfer was calculated using Woschni correlation. By ensuring that the total quantity of heat transfer from local heat transfer model is always equal to Woschni correlation at every crankangle, the undetermined coefficient C() was obtained. The improved model was applied to a singlecylinder watercooled natural aspirated fourstroke direct injection diesel engine. The simulation results are satisfactorily in agreement with the experiment.
