Analysis of Laminar Mixed Convective Plumes Along Vertical Adiabatic Surfaces

Abstract

Laminar mixed forced and free convection from a line thermal source imbedded at the leading edge of an adiabatic vertical surface is analytically investigated. Temperature and velocity distributions in the boundary layer adjacent to the adiabatic surface are presented for the entire range of the buoyancy parameter from the pure forced to the pure free convection regime for fluids having Prandtl numbers of 0. 7 and 7. 0. For buoyancy-assisting flow, the velocity overshoot, the temperature, and the wall shear stress increase as the plume's strength increases. On the other hand, they decrease as the free-stream velocity increases. For buoyancy opposing flow, the velocity and wall shear stress decrease but the temperature increases as the plume's strength increases.
