Drying of a coated paper is modeled and simulated.The paper sheet is assumed to form three zones,and each zone has its own drying mechanism.Coupling of energy and mass balances must be used in order to solve differential equations.The simulations are carried out in various drying conditions i.e.,only hot air drying,only radiant drying,and mixed hot air-radiant drying.Also the effect of one side and two side assumption on evaporation is studied.Effect of venting air speed and radiant heat source presence and its distance from the drying surface on the drying of a coated paper has been studied.It is found that both distance and venting air speed are inversely related to drying in mixed hot air-radiant drying.Both surfaces participate in evaporation however,during the last time of drying,no difference between the upper and the bottom surfaces exist. 展开更多
