Hi guys,
Has anyone in here did simulation flow for turbine, especialy turbine pelton ? how to find the torque when water fluid hit a blade and get the output power.
i get refrence from this website : https://www.engineersrule.com/solidworks-flow-simulation-turbomachinery/
but that for pump.
i have doing it but i'm worry if my simulation is not correctly,
might anyone can share your experience about this.
Thanks You
Define a Surface Goal where you select the following:
1. Solid Bodies that define where the torque is being generated. (Solid bodies are easier than selecting each individual surface.)
2. The correct component of torque.
3. If the axis of your part don't align with the global coordinate system (CS), then first define a local CS, and then select it to complete your definition.
4. To obtain power, define an Equation Goal. See more detail on this below.
To define the Equation Goal correctly for Power=Torque*angular speed
a) Select the Torque value from the list of goals above. Note that I changed the name of the Surface Goal to Tz, so unless you do the same your equation may show the default name.
b) Click on Input Data to reveal the "Add Simulation Parameter" box on the right, under Rotating Regions, expand until you see Angular velocity and double click this to add to the equation.
c) To convert to HP, the conversion value is 5252 (actually 33000/2*pi). For SI units, use the equation {Tz}*2*π*{Rotating Region 1:Angular velocity:1.600e+01}/60. Ref link.
d) Lastly, make sure to change the resulting unit to "Total heat flow & power," which just conveniently happens to be the next in the list after torque.
