Axial and Radial Force Control for a CO2 Scroll Expander

Optimal Control of Exhaust Recovery Generator System with Scroll Expander

A scroll expander exhaust recovery system with the battery is proposed to improve exhaust recovery efficiency. Based on the exhaust flow, storage pressure and the battery current, expander supply pressure was optimized with the loss model based on the expansion and generator loss. And then the supply pressure controller was designed to track the optimized supply pressure reference using the inp...

A Scroll Expander with Heating Structure and Their Systems

A New Ericsson Cycle Comprising a Scroll Expander and a Scroll Compressor for Power and Refrigeration Applications

Conceptual Design of Scroll Expander-Compressor for Stirling Engine

Conceptual design of scroll expander and scroll compressor for 10 kW-class Stirling engine utilizing solar energy as heat source has been carried out. CO2 was chosen as the working fluid, since it is nontoxic, inflammable and it has relatively higher density among probably usable gases. Gas temperature at the expander inlet was set at 700 C, and that at the compressor inlet was at 40°C. System ...

Experimental Investigation of a Hermetic Scroll Expander-Generator

This paper describes a 1 to 3.5 kWe hermetic scroll expander-generator modified from a standard hermetic compressor, an organic Rankine cycle test facility built to test expanders up to 1 0 kWe and a set of experimental results using HCF 134a in the dry vapor domain. Peak overall isentropic efficiencies in the range of 63 to 65% for speeds of rotation varying between 2400 and 3600 rpm are repor...
