Abstract: Transient conjugated heat transfer in thick walled pipes for thermally developing laminar flow is investigated involving two dimensional wall and axial fluid conduction.The problem is solved numerically by a finite difference method for hydrodynamically developed flow in a two regional pipe, initially isothermal in which the upstream region is insulated and the downstream region is subjected to a suddenly applied uniform heat flux.A parametric study is done to analyze the effects of four defining parameters namely, wall thickness ratio, wall-to-fluid thermal conductivity ratio, wall-to-fluid thermal diffusivity ratio and the Peclet number.The results are given by non-dimensional interfacial heat flux values, and it is observed that, heat transfer characteristics are strongly dependent on the parameter values.
