Non-nominal conditions in a radial turbine
I'm simulating a radial turbine.
For nominal conditions (no angle of incidence) the calculations perform well.
When i switch to non-nominal conditions (with a bit of incidence), the results are unrealistic (the efficiency is higher than for the ideal case). I also have to decrease the under-relaxation factors to obtain convergence.
Should I use a unsteady simulation to predict vortex shedding?
