Say I have a sphere of radius r that has a constant surface temperature of T_s.

The sphere is surrounded by air at a constant temperature T_amb.

I am interested in the temperature gradient surrounding the sphere.

From the little I know, I think i have to look at the natural convection and radiation.

I can calculate the heat transfer by using newtons cooling law and the law for radiation,

but I do not know how to calculate the temperature gradient.

Could someone please point me in the right direction?

Much appreciated!
