Buoyancy crossflow effects in the boundary layer on a heated horizontal cylinder
Abstract
An exact solution is presented of the threedimensional laminar boundary layer over a heated surface when gravitydriven buoyance effects introduce significant cross flow into an otherwise axially symmetric flow geometry. The physical model for the study is a semiinfinite cylinder which is aligned with its axis parallel to a uniform flow and normal to the direction of gravity. The obtained equations indicate that the crossflow effect on heat transfer and shear stress for a heated horizontal cylinder grows rapidly when the fluid flows downstream.
