Hi everybody!

I would like to simulate a pipe flow with two inflows ( first inflow cold 10 ; second inflow 54C) and one outflow with the mixture of both (at 37C).

I'm using icoFoam solver modified to solve temperature equation.
The inlet where I have hot water, which enter at a velocity of 0.026 m/s, is inclined at an angle of 110.
- Do I have to decompose the velocity along the axis, to enter it in the 0/U file?
- which kind of pressure bundaries I have to use?
- which kind of physicalProperties do I have to use? Thermal diffusivity and kinematic viscosity at which water temperature?

Sorry for the elevate number of question... i'm new to OpenFoam!!
thank you very much
