Hello,

I am calculating a heat transfer-problem and want to use the heat transfer coefficient. In the user guide of CCM+ the following equation is written:
q_s´´= (rho_f * c_p * u_tau)/(T+) * (T_s - T_c)
(In Version 10.06 it is equation (404))

The heat transfer coefficient is:
(rho_f * c_p * u_tau)/(T+)

But does anyone know where this equation is coming from?

Thanks a lot for your help
