Theoretical and Experimental Analyses of the Internal Leakage in Single-Screw Expanders

International Journal of Refrigeration, 2018
Abstract A single-screw expander (SSE) is a type of volumetric expander that can be applied to power generation, which is beneficial for energy conservation and environment protection. Investigating the SSE leakage characteristics is necessary because leakage has a significant influence on the SSE performance.
