Intro to Engineering Independent Project.
A Tesla turbine is a bladeless turbine that runs on the boundary layer effect. Water is pumped in through the nozzle, grabs the edges of the disks, and causes a high rpm spin to be imparted . The disks are attached via small neodymium magnets to create a single spinning column, and slowing water falls into the center of the cd case. There, holes drilled in the shaft allow for the exit of the water (and reuse, in a more practical design).
The upper part of this design is simply a plastic tub with a cd stack magnetically coupled to the magnets inside the turbine. This allows for the spinning of the disks to translate into useful energy. In this case, I just poured some water in the tub and showed the vortex it would create when spinning.
