Can you provide more links and technical details please? That would make it easier for us to address your question. Thanks.Storm_Eagle said:Hi. I have read about Tesla turbines. What i have found is that it is actually weary little research published on the subject. And as i understand it the main problem with them is the inefficiency in the nozzles used. While the turbine rotor efficiency in it self is really good.
But what exactly makes the nozzles people have tried using inefficient?
Well for example this report:berkeman said:Can you provide more links and technical details please? That would make it easier for us to address your question. Thanks.

A Tesla turbine nozzle is a component of the Tesla turbine, an unconventional type of turbine invented by Nikola Tesla in the early 20th century. The nozzle is a series of small, closely spaced discs that direct the flow of fluid into the turbine.
The nozzle in a Tesla turbine is responsible for directing the flow of fluid into the turbine, creating a vortex that drives the rotation of the discs. It is a crucial component that helps to maximize the efficiency of the turbine.
One of the main problems with Tesla turbine nozzles is that they are prone to clogging. The small gaps between the discs can easily become blocked by debris or sediment, which can greatly reduce the efficiency of the turbine. Additionally, the high speeds and pressures involved in the turbine's operation can cause erosion and wear on the nozzles over time.
To prevent clogging, regular maintenance and cleaning of the nozzles is necessary. Additionally, using a filter or pre-filter to remove larger debris before it reaches the turbine can help. To address erosion and wear, materials with high resistance to corrosion and abrasion can be used for the nozzles, and the design of the turbine can be optimized to reduce the impact on the nozzles.
While the original Tesla turbine design uses metal discs for the nozzles, there have been some alternative designs that use ceramic or plastic discs instead. These materials can offer better resistance to erosion and corrosion, but they may also have lower strength and durability compared to metal nozzles. Ultimately, the choice of material and design for the nozzles will depend on the specific application and operating conditions of the turbine.
