Transient heat transfer for laminar and turbulent boundary layer flows with effects of wall capacitance and resistance
Abstract
Transient forced convective heat transfer from both laminar and turbulent boundary layer flows over a flat plate with appreciable thermal capacity and resistance is studied analytically. For the case of the conjugated fluid-solid system associated with a laminar flow, the integral method is utilized to reduce the systems of nonlinear differential equations to a single integro-differential equation in terms of the interfacial temperature which is then solved with the aid of a finite difference technique. For the case of fully turbulent flow, the principle of surface renewal is employed together with the integral method. Furthermore, predictions are given for the transfer coefficient for turbulent flow over a flat plate of finite length which accounts for the laminar leading edge effect. Numerical results for the fluid-solid interfacial temperature, heat transfer coefficient and temperature distributions within the fluid and the solid are presented.
