Spacer, Boundary layer, Disc turbine, Tesla Turbine, Turbo machine.Abstract
The tesla turbine was invented by Nikola Tesla in 1913, is a non-conventional bladeless turbine which works on the principle of boundary layer. It consist of a number of parallel discs fixed on a shaft with gap between the discs. The fluid is made to flow tangential to the discs inside a casing. Momentum is transferred from to the discs due to viscous and adhesive forces. Not much work has been carried out in the first half of twentieth century but decent amount of published research and study has been done in the latter half. Some papers suggests for modifications while some papers provide explanations for different performances and efficiencies at various parameters. This paper intends to review the principle, working, design modifications and the factors affecting the performance of Tesla turbine.
