Tesla Bladeless Turbine Working Principle 3D Animation

The maverick engineer Nikola Tesla made his contribution in the mechanical engineering field too. Look at one of his favorite inventions — a bladeless turbine, or Tesla Turbine.

The Tesla turbine had a simple, unique design, yet it was able to beat the efficiency levels of steam turbines at that time. Normal turbines are complex in design, with blades of complicated geometry and stator parts. Watch the video from Lesics for more info:

Nikola Tesla once said the Tesla turbine is his favorite invention and he even claimed an efficiency level of 97% for this turbine. Let’s start a design journey to understand this interesting piece of technology, and towards the end we will also verify Tesla’s efficiency claim.

A Tesla turbine consists of a set of smooth disks, with nozzles applying a moving fluid to the edge of the disk. The fluid drags on the disk by means of viscosity and the adhesion of the surface layer of the fluid. As the fluid slows and adds energy to the disks, it spirals into the center exhaust. Since the rotor has no projections, it is very sturdy.
