| Summary |
"The object of this work is an experimental investigation into the possibility of obtaining an increase in the forced convection heat transfer coefficient for a pipe by passing the fluid through narrow transverse slots cut in the pipe, and thereby altering the boundary layer pattern. Since the greatest barrier to the flow of heat from a solid to liquid exists at the boundary layer, it can be expected that any device which will alter the boundary layer pattern will alter the heat transfer coefficient. When mass crosses a boundary layer in a direction perpendicular to the main motion of the fluid, the magnitude and direction of the mass transfer affect the properties of the boundary layer. Experiments with compressible fluids have shown that, in general, mass transfer from fluid to the wall ("suction") increases the magnitude of the transfer coefficients. In this work it is attempted to apply this principle to incompressible fluids"--Introduction, leaf 9. |
