The bladeless turbine has a promising future as a new power generation system. To explore the operating characteristics of the turbine, a bladeless turbine experimental platform with an incompressible working medium was designed and built. The relationships among performance parameters were analysed in experiments, and studies were conducted on the flow characteristics of the working medium inside the turbine using numerical simulation software. The causes of entry and exit losses were analysed. The data acquired by simulation were consistent with the result of calculations using the partial loss model developed in this article, which means that this model is capable of calculating the partial loss of a bladeless turbine and is thus suitable for the design and optimization of bladeless turbines.
