Project Title Working Fluids and Their Effect on Geothermal Turbines
Project Type / Topic 1 Laboratory Call for Submission of Applications for Research, Development and Analysis of Geothermal Technologies
Project Type / Topic 2 Working Fluids for Binary Power Plants

Project Description With design of heat exchangers and turbines to minimize losses based on the second law of thermodynamics, cycles running with relatively cool geothermal fluids can be improved. This proposal intends to enhance the performance of geothermal turbine cycles through improved working fluids and improved use of cooling options, by taking advantage of expertise in prediction and measurement of thermodynamic properties, and accurate modeling of complex turbine cycles based on those properties.
State Tennessee
