kar is on a distinguished road
today I obtained identity of heat source caused by fluid friction for incompressible fluid, but I am not sure, if it is correct.

Here it goes (W / m^3 ):

q == div( mu U & ( grad(U) + grad(U)^T ) )

== grad(U) && (
grad( mu U ) + (grad( mu U ))^T
+ mu U & ( div( grad(U) ) )^T

Please check this,
