An upgraded Tesla turbine concept for ORC applications
Energy, 2018Abstract The Tesla turbine is an original expander working on the principle of torque transmission by wall shear stress. The principle – demonstrated for air expanders at lab scale - has attractive features when applied to ORC expanders: it is suitable for handling limited flow rates (as is the case for machines in the range from 500 W to 5 kW), it ...

Tesla Turbine Torque Modeling for Construction of a Dynamometer and Turbine [PDF]
, 2011 While conventional turbines have been extensively researched and tested, Tesla and boundary layer type turbines have not. In order to construct a dynamometer, thermodynamic flow apparatus and future turbines, we modeled the Tesla turbine using theoretical calculations and preliminary experiments. Thus a series of experiments were run to determine stall

A theory of Tesla disc turbines
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2012In the present article, a mathematical theory for the flow field within a Tesla disc turbine has been formulated in the appropriate cylindrical co-ordinate system. The basis of the theory is the Navier–Stokes equations simplified by a systematic order of magnitude analysis.
