Abstract

When there is no heat source,we analyze the downward trend of surface water and inner water by calculating heat dissipation and heat absorption.here are heat exchange between surface water and air,surface water and inner water,inner water and hot water,inner water and bathtub wall.They can be calculated through enthalpy difference formula,heat conduction formula and principle of minimum increase of entropy.Then, according to heat balance equation,relationship between flow rate of hot water and time is obtained in inner model.Relationship between temperature of surface water and time is obtained in surface model.Human action accelerates wind speed,we calculate new heat dissipation in evaporation.According to formula of thermal resistance of air layer, we can get thermal resistance of air layer.According to numerical analysis, we draw conclusions.When there is no heat source, the water temperature first decreases linearly,then tend to be gentle.Surface water drops faster than inner.
