Fixed mean temperature boundary condition for developing flow

My problem is to implement a temperature BC for the outlet of a developing flow in a channel when there is a constant heat flux at its walls. As we know the gradient of mean temperature is fixed. I tried fixedGradient and applied the fixed gradient to all profiles but it does not work, specially for high prandtls. I also tried fixedMeanValue but it does not work too!!
Is there a BC in openFoam to implement fixed mean temperature or fixed gradient mean temperature?

You should use second derivative boundary condition in your case(d2t/dn2 = 0) . if you google for those words you will find it!!!
