Abstract

In the current study a connected expander – compressor system is investigated. The system is a novel development of such systems to extract mechanical energy from low enthalpy sources, e.g. thermal water, geothermal sources. The system consists of an expander in which warm air expands and flows toward a compressor stage. The connection between the devices has a heat exchanger, thus cooled air is introduced to the compressor. After compression the flow exits the compressor at around atmospheric conditions. During the investigation the Computational Fluid Dynamics (CFD) model of this system is built. The heat exchange in the connecting duct is modelled as an idealised heat exchanger with no pressure loss and perfect efficiency. The aim of the investigation is to find out the flow related parameters and efficiency of the whole connected system with the help of CFD simulations.
