Radial turbine problem
Hi, i'm new in this matter and so i've some questions.
I'm studing a radial turbine that expands a compressible fluid. Though the pressure at discharge of turbine is less than inlet, both the velocity magnitude and relative velocity magnitude on the outlet are bigger than inlet. Is it possible?I analyze its with fluent. Thank you so much. |
Relative velocity should increase (converging passage blade-to-blade) and absolute velocity should decrease (work is being done, velocity energy is being converted to work). Ensure that solution is full converged and settings (e.g. rotation direction) are OK
|
Thank you so much!For convergence i'm testing with steady simplec implicit...step by step increasing inlet total pressure, outlet static pressure and rpm.Is it right??
|
Put the required values of total pressure at inlet and static pressure at outlet, however, increase rpm in steps.
