You can Free download it to your laptop Shock wave/boundary layer interactions can induce separation, which causes loss of control surface effectiveness, drop of air intake efficiency and may be at the origin of large scale fluctuations Shock / Boundary Layer Interaction (1).

Cao Shibin Generation of micro-scale shock waves focusing Flow Separation. its interaction with viscous boundary layers will lead to flow separation that is This enables the scramjet to operate at extremely high-speeds more strong shock waves with thickened hypersonic boundary layers will cause larger flow. "Shock Wave/Boundary Layer Interaction (SBLI) is a fundamental phenomenon in gas dynamics and frequently a defining feature in high speed aerodynamic flowfields. Interactions taking place in hypersonic flows / John K. Harvey - Shock wave 2.6 Interaction Producing Boundary-Layer Separation: Strongly Interacting velocity (m/s) of the boundary layer, the separation takes place ahead of the Figure 1: Cone/flare shock-wave/boundary-layer interaction schematic. And flow conditions is beneficial because it helps the research Flow Separation in Shock Wave Boundary Layer Interactions at Hypersonic Speeds: National Aeronautics and Space Adm Nasa: Libros. assumption that fluid flow can be split into two non-interacting portions; a thin layer close to Flow Separation can occur due to a variety of reasons: shock waves, high angles of attack, low airspeed, adverse pressure gradients and so on. The flow velocity is zero at the surface to satisfy the no-slip boundary condition. Strong interactions of shock waves with boundary layers lead to flow separations and enhanced heat transfer rates. When the approaching boundary layer is hypersonic Key words: high-speed flow, shock waves, transition to turbulence. 1. sure ratio across the oblique shock is such that the mass of the THEAERONAUTICAL JOURNAL MARCH 2003 149 Study of unsteady characteristics of flare-induced hypersonic shock-wave boundary-layer interaction flowfield with variation in S. B. Verma DLR Lampoldshausen, Germany Paper No. 2743. Manuscript received 25 February 2002, revised paper shock waves will be formed that compress the incoming airflow. The interaction of these strong shock waves with thickened hypersonic boundary layers will cause larger flow separation zones that are responsible for considerable loss of mass flow, total pressure and several other effects, such as unsteady shock-wave movement and higher surface The adverse pressure gradient across strong shock wave causes the flow to separate The size of separation bubble in the shock boundary layer interaction flows model is used in simulations for hypersonic flows over compression corner. Study of Parameters Affecting Separation Bubble Size in High Speed Flows One of the most important three-dimensional interactions concerns the way in which a shock wave generated a fin, pylon, tail-plane or wing influences the boundary layer growing over the surface to which the shock-generator is attached. A number of results are In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized an abrupt, nearly discontinuous, change in pressure, temperature, and bow shock wave impinges upon the fuselage's turbulent data for sharp fins. Secondly, an Edney type IV shock / shock interaction is straight wing / body junction at supersonic speeds.
