Simulation of Heat and Fluid Flow in the Single Screw Extruder with Coupling of the Metering Section and Die

단축 스크류 압축기에서 계량화부와 다이를 동시에 고려한 열 및 유동해석

In the present study, the analysis on heat and fluid flow in the single screw extruder is carried out by simultaneously considering the metering section and the die. The finite difference method and the finite volume method are applied to the metering section and the die, respectively. The zonal method is used to couple the metering section and the die. To investigate the effect of die on the characteristics of heat and fluid flow in the single screw extruder, the pressure back flow is included in the analysis. The screw-tip rotation is also considered by employing the quasi 3-dimensional die model. The present results are compared with the numerical and experimental data available in the literatures.
