Computer the Data Simulation of Heat Transfer Analysis of High Viscosity Varying Properties Fluid in Tube

Heat transfer process of high viscosity varying property fluid is widely occurred in production .It exerts a tremendous influence to the quality of the product and the energy consumption . To discuss the regular pattern of heat transfer of high viscosity varying property fluid deeply is of great importance. In this article , we adopt SIMPLER method ,take styrene-polystyrene as an example and make a simulating calculation of heat transfer of a high viscosity pseudo- plastic fluid in the tube. The result that the pressure drop is relatively much influenced by the physical properties . To select smaller tube diameter is the effective measure to reduce radial temperature difference.
