| Abstract: | A three dimensional isothermal flow field model was established for the power law fluid in the melt conveying zone in an intermeshing counter rotating twin screw extruder. The flow field was simulated by FEM(finite element method) package of ANSYS obtaining the profiles of the velocity, pressure and viscosity of the melt fluid in the extruder. The effect of the different geometrical variables and operational conditions on the operating characteristics of the extruder was analyzed. |
