Abstract
The main objective of the project proposed in this course is the study of microscopic effects on a Tesla turbine's discs. This will be done by means of a small-scale model of a Tesla turbine which will be built. Of special consideration is the discs' roughness, which is responsible for adherence of the working fluid. The study employs as a basis for its approach the concepts learned in Fluid Mechanics, with the Boundary Limit Theory as a primary focus as this is relevant to the type and quality of the disc surfaces used. In this way it was possible to analyze factors that are intrinsically linked to Mechanics of Solids, such as surface roughness. The methodology used first involved computer software to model the Tesla turbine, then experimental tests were conducted to better understand how fluids behaved as results were compared from the four different sets of rotors. The torque output of each disc type was then determined using the ideal surface roughness of a disc as the baseline. The project's secondary objective was to increase the efficiency of the Tesla turbine by mitigating losses, such that the electricity generated can potentially be used in remote areas.
