The paper presents an analysis of a Tesla bladeless turbine for a co-generating micro-power plant of heat capacity 20 kW, whichoperates in an organic Rankine cycle with a low-boiling medium. Numerical calculations of flow in several Tesla turbine models areperformed for a range of design parameters. Results of investigations exhibit interesting features in the distribution of flowparameters within the turbine interdisk space. The efficiency of the Tesla turbine depends on many parameters, including thepressure, temperature and velocity conditions, rotational speed of the rotor as well as the number, diameter, distance between thedisks and the state of the disk surface and finally the number and arrangement of the supply nozzles. The calculated flow efficiencyof the investigated Tesla turbine models show that the best obtained solutions can be competitive as compared with classical smallbladed turbines.
