Hi guys,
i would be very thankful to all if anyone is there to tell what can the velocity inlet zone conditions be given for multiphase liquids (i.e. open channel flow) and in which option in fluent ??? Please also tell about how we can do animations for a fluid flow in Graphics and Animations option???? |

just chose multiphase model. and then provide the volume fraction of the secondary phase. The BC is independent of the flow regieme and it works for all multiphase flows. So u can do it Animation files i have posted about that several times. Check previous posts. shk |

Dear all,
the problem is that i have an open channel of rectangular cross section and is axis has some inclination downwards. I have done its design modelling as well as meshing. I have the inlet velocity and pressure outlet. I don't know what the zone conditions should be given to this open channel? I am at zero level in giving the zone conditions. Kindly help me. I will be highly obliged to all for your help. |

hi,
i am doing fluent simulation for multiphase flow in fluidized bed reactor. the iteration is going on. but some message is showing in between the iterations like "reversed flow in 28 faces on outflow 6" and "reversed flow in 24 faces on outflow 6". what is the meaning of this message..can anyone help me ? |

For Pressure outlet you need not any thing to specify and let it be! Let us know how it goes on!! Also you'd better to take a look at Fluent tutorial. It has some very good examples. Bests. |

hii!!
Can someone help me the velocity inlet conditions... I have patched the voleme fraction of water to the bottom register but cannot get the flow to converge... i guess some problem with the BC. Please help. I have velocity inlet and pressure outlet . i have kept the top surface as velocity inlet. |
