Technical field
The present invention relates to the fields of the stream solid multi-crossed disciplines experimental study such as shock wave damage, more particularly to a kind of shock wave
Pipe Test Data Collecting analysis system.
Background technique
Strong compressional wave in supersonic flow, faint disturbance is propagated around with local velocity of sound in gas.Work as flight
When device is with subsonic flight, spreading of disturbance is bigger than vehicle flight speeds, so disturbance can not concentrated, it is at this moment entire to flow
It is continuous that flow parameter, which includes the distribution of flow velocity, pressure etc., on field；And when aircraft is with supersonic flight, disturbance has little time
It passes to before aircraft and goes, as a result compression of the gas of front by aircraft jumping, forms the strong disturbance of concentration, at this moment
There is the interface of a compression process, referred to as shock wave.
Shock wave is the superposition of for example weak compressional wave of micro-disturbance and the strong discontinuity formed, has very strong nonlinear effect.By
Shock wave, the pressure of gas, density, temperature can all increase suddenly, and flow velocity then declines suddenly, and rising to for pressure generates the quick-fried of audible
It rings.When making supersonic flight in lower airspace such as aircraft, the people on ground can hear this sound, i.e., so-called sonic boom.
Using the characteristic by the mutation of shock wave gas density, shock wave can be filmed with optical instrument and see wind-tunnel measurements method.Reason
Think that the shock wave of gas does not have thickness, is the discontinuity surface of mathematical meaning.Real gas toughness and conductivity of heat, this physical property
Shock wave is set to become continuous, but its process is still very hurried.Therefore, practical shock wave has thickness, but numerical value is very micro-
Small, only some multiple of gas molecule free path, the opposite over-one Mach number of wavefront is bigger, and thickness value is smaller, and how
The experimental data in shock tube is recorded and analyzed in real time, and the safety of guarantee test becomes urgent need to solve the problem instantly.
