We consider the laminar boundary-layer flow past a semi-infinite plate with a stream-wise ridge. We seek similarity solutions to the problem, when the freestream velocity takes the form x* n, where x* ...

The theory of compressible flow in a laminar boundary layer has been developed for the case when the viscosity is assumed to be proportional to the absolute temperature and the Prandtl number is unity ...

Figure 1. On the left, filtered Rayleigh side-view images of boundary layers at Mach 8. The flow is from left to right. The Reynolds number based on momentum thickness is about 3,600. On the right, ...

Laminar boundary layers are needed to advance hypersonic flight to a new generation, according to a significant paper from NASA, the Air Force Research Lab and Case Western Reserve University ...

This includes a set of video cameras monitoring the reflection on the laminar-flow wings' surface of a black-and-white stripe pattern painted on to a fairing between the conventional and new sections.

The system then generates suction to maintain the laminar flow. Another interesting feature of the 787-9 is its high-lift system, which has been adapted from the 787-8 to cater for higher ...
