abstract = "It is generally recognized that the physical phenomena related to
the problem of separation are very important in the design of
hypersonic configurations. When separation occurs in high Mach
number flows, the changes in pressure distribution and heat
transfer rate can have catastrophic effects in the vehicle. The
presence of hot spots at separation and reattachment points
changes the characteristics of the flow over the vehicle and can
cause failure in the thermal protection system, as was evidenced
by the tragic loss of Space Shuttle Columbia in 2003. In general,
separation occurs due to the interaction of external flows with
various desired or undesired design features present on the
vehicle surface, such as protuberances, notches, cavities, gaps,
or steps.",
