[Simulation Analysis for Polymer Processing by PC (3), Japan Plastics, Vol.50, No.1, P.147 (1999)]
To analyze flow and heat transfer of polymer fluid precisely, viscous heat generation and heat transfer of non-Newtonian fluid flow shall be considered. In such cases, heat transfer, internal heat generation, temperature and shear rate dependency of fluid viscosity are to be taken account. This level of analysis is worthy of saying "simulation". Numerical method of getting temperature change, temperature distribution and pressure drop of non-Newtonian fluid in circular tube under constant surrounding temperature is discussed in this chapter. This is one of the most fundamental techniques of polymer processing analysis, and is simple but useful having high utilization. This method will be a good reference when using similar technique, and is discussed in some detail here. |
