Calculation of the tangential forces in a turbine blade

Click For Summary
SUMMARY

The calculation of tangential forces in turbine blades can be performed using the formula Ft=(1000*P)/(e*v*z), where P is the stage power (1413 kW), e is the partiality degree, v is the circumferential velocity, and z is the number of blades (45). To find the circumferential velocity, it is necessary to convert the operating speed of 3000 RPM into meters per second. This static analysis can be conducted using ANSYS software, which is essential for simulating the performance of turbine blades under specified loads.

PREREQUISITES
  • Understanding of static analysis in ANSYS
  • Knowledge of turbine blade mechanics
  • Familiarity with rotational dynamics and RPM conversions
  • Basic proficiency in using engineering formulas for force calculations
NEXT STEPS
  • Research how to convert RPM to circumferential velocity in meters per second
  • Study the impact of partiality degree on turbine blade performance
  • Explore advanced features of ANSYS for turbine blade analysis
  • Learn about the effects of axial load on turbine efficiency
USEFUL FOR

Mechanical engineers, turbine design specialists, and anyone involved in the analysis and optimization of turbine blade performance will benefit from this discussion.

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.
