Discussion Overview
The discussion revolves around the calculation of the area relevant to the power output of a Tesla turbine, as referenced in a specific paper. Participants explore the implications of the formula provided and its applicability to Tesla turbines, which consist of discs arranged with gaps.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- One participant references a paper that includes a formula for power output and seeks clarification on whether the area should consider only one side of a disc or both sides across all discs.
- Another participant points out that the equation mentioned is on page 12 of the paper and suggests it may not be directly applicable to Tesla turbines, indicating it refers to a general flow section.
- A third participant expresses doubt about the equation's ability to accurately describe the output of a Tesla turbine, noting the differences in driving forces compared to conventional turbines.
- One participant agrees with the skepticism regarding the equation's applicability and adds that Tesla turbines are generally inefficient due to boundary layer drag and back pressure issues, questioning their justified use.
Areas of Agreement / Disagreement
Participants express disagreement regarding the applicability of the formula to Tesla turbines, with some questioning its relevance and others agreeing on the inefficiency of Tesla turbines in general.
Contextual Notes
There are unresolved assumptions regarding the specific definitions of area in the context of the formula and the characteristics of Tesla turbines compared to other turbine types.
