Im wanting to run a transient structural analysis of a gas turbine start-up sequence, specifically focusing on the turbine blade. I've run some CFX to find the surface temperature distributions, but now im wanting to couple that with rotational motion from rest until design speed.
Right now my setup is by applying a rotational velocity with a single step where the initial velocity is 0, and the final velocity is 3000 rpm. The time step between these values is 8 minutes. So the velocity chart is linearly increasing, giving a constant acceleration.
Is this the correct way to set up a simulation of a turbine starting from rest until it reaches design speed ? Or am i meant to include more detail in the tabular data setup for the velocity time steps.March 11, 2022 at 12:44 pmViewing 1 reply thread
