Usually, this change is small and has little bearing on the growth of the boundary layer itself. At hypersonic speeds, there can be strong effects of displacement as the heating of the boundary layer gas decreases the …

WebJan 28, 2016 · In lamanar flow, the air flows smoothly across a surface and the streamlines move parallel to each other. A lamanar-flow boundary layer is very thin - possibly only .02 inches thick. As you move up and away from a surface, the airflow's speed smoothly increases in a laminar flow boundary layer until it reaches free-stream speed.
