Abstract: | Coupled heat transfer between laminar forced convection along and conduction inside a flat plate wall is theoretically studied.
The laminar convective boundary layer is analyzed by employing the integral technique. The energy equations for the fluid
and the plate wall are combined under the condition of the continuity in the temperature and heat flux at the fluid-solid
interface. The analysis results in a simple formal solution. Expressions have been obtained for calculating local Nusselt
number, wall heat flux and temperature along the plate, all are functions of the local Brun number, Br
x
, which is a measure of the ratio of the thermal resistance of the plate to that of the convective boundary layer. The results
indicate that for Br
x
≥0.15, neglecting the plate resistance will results in an error of more than 5% in Nusselt number. Comparison of the present
solution with other previous studies has been made. The solution may be of a considerable theoretical and practical interest.
