Turbulence pressure in convection zone

[Helios]

Is there a formula for turbulence pressure that is a function of temperature ( in the convection zone of a star )?

I didn't look at the whole thing yet, but it should be on:

The complexity of that is far too daunting. I want to avoid time-dependence and certainly magnetism. Frankly, I'll tell you what I'm working on and that is a composite polytrope; n=3 inside and n=1.5 for a convective envelope. Now I would like to be able to point to some term in an equation and say this part is due to convection. My articulation is vague at this point and I would welcome any ideas.
