Mathematical modeling of torque for single screw expanders

Journal of Mechanical Science and Technology, 2017
This paper presents a mathematical model of torque for Single screw expanders (SSEs). Instantaneous torque and torque ratio were analyzed and discussed. The periodic variation of instantaneous torque is the same for different inlet pressure levels. The torque ratio, with its value close to 1, is independent of the inlet pressure of SSE. An experimental

Numerical investigation of flow behavior and film thickness in the single screw expander

International Journal of Mechanical Sciences, 2021
Abstract The need to understand the flow behavior and film thickness in the single screw expander is very crucial since it is known to be a complex system due to the existence of various flow patterns. The present work reports a computational fluid dynamic analysis of two-phase flow behavior and film thickness through a vertical helical rectangular ...
