Jet pipe refers to the geometry by changing pipeline section inner wall to accelerate a kind of device of fluid.Common jet pipe has two
Kind: one is convergent nozzle, another kind is de Laval noz(zle), or is Laval nozzle.
Influence of the nozzle section variation to flow velocity is as follows:
By continuity equation:
By the equation of momentum:
Two formulas merge, and obtain:
In formula: ρ fluid density, V fluid volume, A sectional area, M Mach number.
Fluid Mach when compressible fluid (calling fluid in the following text) is in critical and supercriticality, on nozzle exit section
Number is equal to 1, and outlet is critical cross-section, reaches maximum value by the mass flow of jet pipe.Since outlet is the velocity of sound, because
And when back-pressure further decreases, the fluid Mach number on outlet cannot be made to continue to increase, jet pipe quality stream can not be made
Amount continues to increase, therefore flow reaches maximum value, and the flow regime of M=1 is state of being jammed.Once jet pipe is in state of being jammed,
Nozzle exit external world back-pressure just can no longer influence the flowing in jet pipe.Moreover, either changing the extraneous back-pressure in outlet, or change
Stagnation pressure, the total temperature for becoming inlet fluid, all cannot make the dimensionless group in jet pipe on any section change.
