Hello Foamers and Researchers!!
Greetings! I am quite new to OpenFoam, has been practicing it from last 1 month. I have a doubt and I would be very grateful if anyone can help me with this. In a problem I have given flowRateInletVelocity boundary condition at my inlet, specifying mass flow rate. fixedFluxPressure BC is given for pressure at the inlet. I want to know that if we give mass flow rate (or volumetric) BC then how the velocity profile at inlet will be decided? (Parabolic, uniform etc) Regards, Prateek. |

Prateek,
Seems you have double posted, so I'll answer both quickly to let the admin delete one if they like. Have a look at the code in Code:
/src/finiteVolume/fields/fvPatchFields/derived/flowRateInletVelocity/flowRateInletVelocityFvPatchVectorField.C Code:
// mass flow-rate operator==(n*avgU/uniformRho); |

Hello Daniel,
Thanks a lot for the quick reply. I noticed afterwards that I posted this twice. Sorry for the same. Yes I have seen the code as you mentioned and got what you said. My deepest gratitude for sorting out my confusion. Regards, Prateek. |

Hey guys,
Do you know how to set the mass flow rate NOT normal to the boundary? B |
