CFD Solutions of High Prandtl Flows Using Boundary Layer Similarity

When attempting to resolve the flow over complex geometries with high Prandtl fluids using CFD, there is a large difference in the size of the hydraulic and thermal boundary layers. This leads to differing requirements for the grid resolution. In fact, resolution of the thermal boundary layer often leads to a grid size that is highly memory intensive. The following paper discusses this problem and outlines a method by which boundary layer similarity may be used as a possible alternative to these large grids.
