Application-Oriented Design and Theoretical Investigation of a Screw-Type Steam Expander

, 2014
Screw expanders offer a high potential for energy conversion in the lower and medium power range, for instance as expansion engines in closed loop power cycles.

Detailed Thermal Model of an Open-Drive Single-Screw Expander for ORC Applications

, 2018
A comprehensive mechanistic model of an open-drive single-screw expander for waste heat recovery applications by means of an Organic Rankine Cycle (ORC) has been previously developed and validated by the authors. The model included sub-models of geometry,

Experimental characterization of single screw expander performance under different testing conditions and working fluids

, 2015
During the last years, one of the most popular ways to recover low-grade waste heat is the organic Rankine cycle (ORC). This technology is widely studied and continuously optimized and, as a result, there are many efficient installations available on the
