The drying skill is very important in national economy. It is widely used in every department,for example,the corn drying in agriculture,the phosphor drying in mine,etc.For many products,during their producing,the drying is so important,and the right drying technology and the right operating are all the key factors to improve products trait.With the development of world economy and technology,the products dosage and output become more and more.At the same time,there become more new products that need being dried.With the higher quality requirement,,the nature manners of the materials and products that were dried in the past are inclined to drying by manpower.Contemporary,there are more and more problems coming up with the drying using.Except removing water from the material,the chemist and the components also have some special requirements , for example, during the corn drying , the requirements of figure,nutrition components , character etc. With the investigations of The World Food and Agricultural Organization,the corn losing caused by incorrect drying manners and deposited is 5~10 percent every year in the world.In our country,we product 4 billion corn one year,but also we loss 30 million every year.All the losing are caused by incorrect drying.So,if we want to reduce the losing,we must solve the drying ways,and this also will reduce the energy consume.It is one very important step after the corn harvest.It is more meaning than spending more time on researching on increasing productions.With the research development,the drying skill of Fluidized Bed has become one very important skill in drying field.Comparing with the other drying skill,it has more excellences.So the Fluidized Bed drying skill is becoming more and more popular now.In the past few years,the CFD theory develop more and more perfect ,and fund devotion become more and more.Many academicians bring forward many models to research the drying process.This article bring forward math model of fluency and heat transfer and quality transfer.I used the FLUENT software to simulate the flow process of air and solid.For the quality transfer research.I...
