帮你把User's Guide的31.4 Alphabetical Listing of Field Variables and Their Definitions 一节相关内容粘在下面，公式不好贴，自己去查。
Wall Func. Heat Tran. Coef.    is defined by the equation
                 Eq.     (31.4-51)
where Cp  is the specific heat,  kp is the turbulence kinetic energy at point P, and T*  is the dimensionless law-of-the-wall temperature defined in this equation in the separate Theory Guide.

Surface Heat Transfer Coef.    (in the Wall Fluxes... category), as defined in ANSYS FLUENT, is given by the equation
                heff = q / (Twall -  Tref )                       (31.4-40)
where q  is the combined convective and radiative heat flux, Twall is the wall temperature, Tref and  is the reference temperature defined in the Reference Values task page. Please note that  Tref is a constant value that should be representative of the problem. Its unit quantity is the heat-transfer- coefficient.
