Hi there,
This more of a general fluid mechanics question, which I've had no luck in finding the answer, but here goes anyway: For cd nozzle with constant pressure condition(inlet, outlet), are there equations to calulate the velocity decrease due to friction in nozzle? I mean that the roughness constant and roughness height causes a frictional pressure drop, but how does this effect the velocity as function of length? Any response will be appreciated. |

For compressible flow in quasi one-dimensional assumption, you can use the Fanno theory with superimposed area variation to set the governing equations

Thank you for your kindness.
Do you have a tutorial about Fluent calculation with fanno theory? If you have that tutorial, Please contact to me. |
