An Integrative Technique for Predicting Cooling Performance of Tanks

The cooling process of tanks relates to various physical actions,parts or components and fluids.A predication method is presented to evaluate the effects of cooling system for tanks.A predication model that includes the heat production,heat transfer and fluid flow modules is established.The engine combustion and friction between components act as the primary heat sources.The solid components of power transmission train are partitioned into thermal nodes.The heat conductions among the thermal nodes,coolant,lubricant,powerhouse fresh air,combustion gas and exhaust gas are taken into account.The coolant flow,lubricant flow and powerhouse air flow are also considered.The prediction model is resolved by use of a multilayer iterative technique and an arithmetic of local convergence combined with global convergence for coupled modules.A calculation example shows that the model can implement predication of cooling system under different environment temperatures and running conditions quite better.
