Investigation on the Geometrical Model of Scroll Expander Based on Circle Involute
摘要
Abstract
The geometrical model for the constant thickness scroll expander based on the circle involute is presented. The modification of scroll profile based on the geometry of the circle involute is discussed. The analytical method is used to calculate the area change of scroll wrap for EA-SAL. The volume and derivative volume of the working chambers with respect to the crank angle are gotten by integral method. The modification of the scroll wrap has little effect on the suction volume but the profile stiffness obviously increases compared with the volume of the suction chamber for modification profile and no modification profile. Finally,the lengths of radial leakage lines are analysed and calculated,the results supply foundation for thermodynamic research of scroll ex1pander.关键词
