A bow shock, also called a detached shock or bowed normal shock, is a curved propagating disturbance wave characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density. It occurs when a supersonic flow encounters a body, around which the necessary deviation angle of the flow is higher than the maximum achievable ...

2012年8月1日 · The bow shock wave shift at electrogasdynamic method has been realized due to a gas discharge in the near-surface region at the nose part of the body behind the shock wave. This method is concerned with the heat action of the discharge.

A bow shock is a supersonic shock created at the sunward side, at which place the solar wind particles are slowed and heated and then take a detour around the Earth in the magnetosheath. From: Physical Chemistry, 2018

to the condition that could be encountered by a hypersonic missile in flight near a nuclear blast. The conservation equations are obtained for a viscous, hypersonic,

A blunt body creates a bow shock wave at high Mach number, which produces a very high in pressure in the forward region of the hemispherical region which leads to an increase of high wave drag during the projectile’s flight through the atmosphere.

In the high speed regimes, a blunt forebody yields a strong detached bow shock wave ahead of it. This shock wave is responsible for the elevated pressure and aeroheating levels attained by the downstream flow.

Bow shock occurs when the magnetosphere of an astrophysical object interacts with the nearby flowing ambient plasma such as the solar wind. For Earth and other magnetized planets, it is the boundary at which the speed of the stellar wind abruptly drops …

2019年9月9日 · In decelerating cases, the bow shock formed in supersonic flight persists in the subsonic regime. The differences in the flow field between the steady and unsteady cases are explained using the concept of flow history. In the experiment, a tubular insert was present near the observation window in the ballistic range.

At Mach 1.5 and above, the oblique shock waves merge to form a strong bow shock wave at the nose of the missile, resulting in a significant increase in drag due to the high-pressure region in front of the missile. Shock waves are formed due to the compressibility effects of the airflow, leading to deceleration and increased air pressure behind ...

These samples quantitatively show how bow shock, fin orientation, fin deflection, and body vortices can produce strong, unusual, and computationally challenging effects on individual fin loads. Flow-visualization photographs are examined to provide physical insight into the cause of …
