abstract

This paper presents the Computational Fluid Dynamics analysis of a Tesla bladeless turbine using compressed air as the working fluid. Multiple flow configurations are analyzed using both Laminar and the turbulent behaviors. The loading coefficient and the efficiency of turbines is evaluated for both the 2D and 3D cases. Multiples disc is a viable option but it is been observed they result in loss in performance for the laminar and turbulent simulations. In addition the inflection point of the laminar flow vanishes in the turbulent flow; the work presented is an initial step towards the realization of Tesla turbine.
