I am starting to simulate a CENTRIFUGAL FAN.
1.I have made the rotor wiht turbogrid 1.6 2.I have made the volute with CFX-Mesh 3.I have put massflow at inlet and pressure at outlet 4.The interface between rotor-volute is a Frozen rotor. Pressure between experimental data and CFX data are quite diferent. could anyone give me advise?? 1.Is it o.k to mesh with CFX-Mesh for volute? 3.Wich type of interface I must put? 4.How I can model the gap between rotor(rotating) and inlet (static) |

Dear sir
This is sudarshan from india. I am doing my MTECH in COMPUTER AIDED MECHANICAL DESIGN AND ANALYSIS. I am doing a project titled " INVESTIGATION OF THE TWO DIMENSIONAL FLOW BEHAVIOUR DUE TO INTERACTION BETWEEN THE IMPELLER AND VANED DIFFUSER IN A CENTRIFUGAL FAN ". The objectives of the projects are : 1) To locate secondary flow vortex. 2) Flow separation under different operating conditions and to establish design point operation of the pump. The software tool used for the above is ANSYS. I need your help for my project work. Can you send me all the research papers involved in my project work. I will be greatful to you if you send me research papers. My email id is sudarshan2683@yahoo.co.in Thanking you, Yours faithfully SUDARSHAN |

Hello,
I do not understand what do you need exactly. Could you specify what do you need? Regards, Txema |

HI ALL,
I WORK ON DESIGN OF CENTRIFUGAL PUMP VOLUTE. 1) I WANT TO KNOW , TO CARRY OUT CFD ANAYSIS USING FROZEN ROTOR ,WHICH IS BEST STEADY STATE OR TRANSIENT..? 2)ANY MATERIAL RELATED TO VOLUTE DESIGN Thanking you, Mangesh |

Frozen rotor is a "photograph" of your problem at this time.
Use Frozen rotor to carry out your simulation at first and then use Transient simulation to get more accurate results. With a transient simulation you can see the interaction between rotor and volute along time with different positions for the baldes. Regards Txema |

hi thanks
I AM GIVING TOTAL PRESSURE AT INLET AND MASS FLOW RATE AT OUTLET. BUT WHEN I CHANGE MASS FLOW RATE , TORQUE IS CHANGE , SO PLZ GUIDE ME FOR OUTLET BOUNDARY CONDITION. |

These boundary conditions are o.k.
The torque, power, and raiting point Pressure-massflow change with massflow boundary condition. Have you ever saw a centrifugal fan plot?? Because this is how fans work. Txema |
