Sinopsis

Velocity and temperature solution for laminar plane wall jet with wall at the base (conjugate problem) has been numerically solved. Velocity distribution has been obtained following non-dimensional meted of Glauert (1956) and found to be exactly matching with the analytical expression. The momentum and energy equations then have been solved following the non-dimensional method of Schlichting (2000) for constant wall heat flux and constant wall temperature. It has been observed that the Nusselt number (Nu) distribution thus obtained matches with the analytical expression given by Schlichting (2000). This formulation is used for study of conjugate condition. Energy equations in the fluid and in the solid have been solved simultaneously to obtain the temperature distribution in the whole field. Parametric study has been done to investigate the effect of the Reynold number (Re), the Prandtl number (Pr), the thermal conductivity ratio (K) between the slab and the fluid medium and the slab aspect ratio (H = h/L) on the heat transfer characteristics.
