Hi guys,
as a beginner, how can I define the Reynoldsnumber for rhoCentralFoam For icoFoam I choosed for Re=10 following parameters: U=(1 0 0) nu = 0.1 D = 1 => Re=20 How can I do this for rhoCentralFoam? Thank you |

Reynold's number is a fundamental flow property and is independent of what solver or code you're using. So the answer would be: you define it in the same way as you did in the example you've posted (I think you have an error there since 1/0.1 = 10, not 20). Still, since you are asking about rhoCentralFoam, which is a compressible solver, you are probably interested in compressibility and so Mach number of your problem will also be important, amongst other things.
Good luck with your case, A |

Thanks, got it already. Re=20 was a silly typo of me :-)
