CFD Online Discussion Forums - How to incorporate inflow velocity as an input file

Dear Foamers

I want to simulate a combustible case with LES in which the fuel jet has a fully developed profile that originates from a 46 m/s velocity. I mean with applying 46 m/s to a pipe we can derive the final fully developed velocity. I do this by extending the inflow as a pipe and let the profile to take the fully-developed shape. However, this culminates into dropped inflow temperature about 10 degrees. Here is my Pressure file:

Code:

internalField   uniform 101325;



boundaryField

{

    inletfuel

    {

        type            zeroGradient;

    }

    inletair

    {

        type            zeroGradient;

    }

    outlet

    {

        type            fixedValue;

        value           uniform 101325;

    }

    burnerwall

    {

        type            zeroGradient;

    }

    outlet2

    {

        type            fixedValue;

        value           uniform 101325;

    }

I have used zeroGradient for the wall of the inflow pipe and the inlet of the pipe.
My Question is that Is there any way to read the inflow data from a saved file and get rid of the dropped pressure and temperature and also increased grid points of the extended pipe for fuel jet?

If somebody has a tutorial for this case would you PLZ attach it for me or if O.F. tutorial has this case, would somebody hint me where it is?
