Calculation of the tangential forces in a turbine blade

AI Thread Summary
To calculate the tangential force on a turbine blade in ANSYS, the formula Ft=(1000*P)/(e*v*z) can be used, where P is the stage power in kW, e is the partiality degree, v is the circumferential velocity in m/s, and z is the number of blades. Given the operating speed of 3000 RPM and stage power of 1413 kW with 45 blades, the circumferential velocity must be determined to complete the calculation. The axial load of 5544 N is also relevant for overall analysis but does not directly affect the tangential force calculation. This approach provides a structured method to derive the tangential force necessary for static analysis. Accurate input values are essential for reliable results in turbine blade analysis.

Dear All,

I am trying to perform the static analysis of turbine blade in ANSYS. And i have a problem with finding the values of tangential force. How can i find it, if have following data: operating speed - 3000 RPM, stage power - 1413 kW, axial load 5544 N, number of blades - 45.

Thanks a lot!

I found this equation. Maybe it can help for someone.
Tangential force Ft can be found using the following formula:
Ft=(1000*P)/(e*v*z), [N];
where: P - stage power, [kW];
e - partiality degree;
v - circumferential velocity in the middle of the height of the blades, [m/s];
z - number of blades.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
