Heatline visualization of forced convection laminar boundary layers.

Summary

The paper reports in closed form the similarity of heat functions for laminar boundary layer flow on a flat wall. Plots of the constant-heat function lines ("heatlines") show that the path of convection from a hot free stream to a cold wall is unlike the path of convection from a hot wall to a cold fluid. The paper stresses the heat transfer features that are brought into view for the first time by the heatline patterns. As a supplementary contribution, the paper reports the exact similarity solution for the wall with uniform flux in the Prandtl number tending to 0 limit, and proposes a closed-form local Nusselt number correlation that covers the entire Prandtl number range.
