Abstract

Heat transfer in the ENGINE should be simulated to have a good estimation of emperature distribution in the ENGINE and therefore control thermal stresses and the ENGINE performance. HEAT TRANSFER simulation is obtainable through accurate modeling of COOLING PASSAGES of the ENGINE. Subcooled BOILING is usually occurred in the COOLING PASSAGES. Ignoring this phenomenon in the modeling procedure results in a considerable error in estimation of HEAT TRANSFER coefficient at the wall. In the present study numerical models for simulation of HEAT TRANSFER in COOLING PASSAGES of combustion ENGINEs are introduced and evaluated. The models, appropriate for simulation of each stage, are then explained and their precision will be calculated. In this study the method of principal convective HEAT TRANSFER is introduced by exerting some modifications on the empirical correlation of Foster-Zuber. The proposed method in this study results in a significant zecrease in amount of calculations and therefore increases the rate of calculation of HEAT TRANSFER and thermal stresses. One of the significance of this model is consideration of BOILING effects in the HEAT TRANSFER coefficient. The proposed model is employed for simulation of HEAT TRANSFER in COOLING PASSAGES of the “EF7” ENGINE to calculate HEAT TRANSFER coefficient and BOILING zones and then proved to have a good precision.
