Heat flux boundary condition in OpenFOAM

Respected Sir,

I have to give uniform heat flux of 3472 W/m2 over a flat plate (named as heatWall) of size 120 mm * 120 mm. The working fluid is air having thermal conductivity, k taken as 0.024 W/mK.



type fixedGradient;

value uniform 144666.67;// This value corresponds to heat flux / thermal conductivity = 3472/0.024 = 144666.67


Is this the way to set the uniform heat flux boundary condition in OpenFOAM? If not, can you help me in setting the correct boundary condition.

Eagerly waiting for your reply.

Thank you.

The "fixedGradient" bc which you gave is the right one to give uniform heat flux bc in OpenFOAM.
