Hi,
I am doing analysis for a steam turbine...so i have three inputs for this case...mass flow at inlet,inlet pressure and inlet temperature....can any one suggest me that which boundary condition i have to choose...

It is compressible fluid..

If i choose my inlet boundary as mass_flow_inlet and here i can give my inlet mass flow and temperature but inlet pressure cannot be given..

If i choose Pressure_inlet as my inlet boundary condition then here i can give inlet pressure and inlet temp only but amount of mass flow cannot be given

Outlet pressure and temp are not known and i have choosen pressure_outlet as my boundary condition,but oulet pressure and temp are unknown

Can anyone suggest me that which boundary condition can be choosen such that i can give my three inlet parameters, ie inlet pressure,inlet temp and mass flow at inlet....and which boundary condition for outlet as well

Thanks & Regards
Sudhir

You have two options here..
1. Use a pressure outlet with target mass flow rate option (not sure if its available with compressible flow though)

2. Use a mass flow inlet as an outlet (you can do that by specifying the direction vector as pointing out of the domain)

Hope that helps,

You need to be more specific on what exactly you need help with! And dont hijack other threads !
