During human space exploration, small-micro power generation technology for space heat sources can be used without relying on solar energy and is a useful option for deep space exploration missions, including manned Moon landings and Mars landings. The Tesla turbine, as a simple micro-expander, has great potential to play an important role in the field of small micro-generation, thanks to its unique structure and principle. In this study, the performance of the Tesla turbine is experimentally tested under different medium and low temperature heat source temperatures, flow rates, and loads. The experimental results indicate that the Tesla turbine and its accompanying power generation equipment, can achieve more than 60% isentropic efficiency and more than 95% shaft efficiency under different operating conditions at pressures below 1.4 MPa, respectively. It provides experimental basis for the future research and application of Tesla turbine.
