What expression should be used to calculate Nusselt number for free convection (of air) in a vertical channel with walls at different temperatures?
I have the Bar-Cohen and Rohsenow equations, but I am unsure which situation this corresponds to (and thus which constants to use).
Symmetric isothermal plates (wouldn't this imply Ts,1 = Ts,2 which is not the case?)
Symmetric isoflux
Isothermal/adiabatic (I am leaning towards this)
Isoflux/adiabatic
