Following is a series of blogs introducing to the basics of the pump cavitation analysis in ANSYS CFX and to automate this process by using CEL (CFX Expression Language) and Perl script.

Hi, I want to simulation the cavitation phenomenon of unsteady in a centrifugal pump by using CFX, can you give me some advice?
thank you! |

Please follow the tutorials as described in this thread, and do the following: 01: Start with a steady state analysis with cavitation model turned off. 02: Then start another steady state analysis with Cavitation model turned on and initialise this analysis from step 01. 03: Strart the transient analysis with cavitation model turned on and initialise this from the results of step 02.

Hi, techCAE
thanks for your reply! I hope to raise another question. As the flow in the centrifugal pump (or other hydraulic) is an unsteady process when in actual operation, can i ignore the second step and in the third step of calculation with the result of the first step as the initial value when start the unsteady cavitation simulation? What's the distinction between the result of this method and yours? I'M looking forward to your reply! regards |

That could be a good learning exercise for you, (if you are at initial stages of that analysis). Please try both and then look at the difference. |
