Steady flow of compressible fluids

Steady flow of compressible fluids

In gases there is a difference between flow at constant volume (incompressible) and flow with varying volume (compressible). For larger changes in the fluid’s pressure and temperature the interconnections between pressure, temperature and volume may not be ignored any more. This flow is called compressible.

HM 230

Flow of compressible fluids

Subsonic and sonic flow through different measuring objects.

Supersonic wind tunnel with Schlieren optics

HM 172

Supersonic wind tunnel with Schlieren optics

Schlieren optics for visualisation of Mach lines and shock waves on drag bodies; interchangeable walls in the measuring section produce velocities up to Mach 1,8.

Characteristics of nozzles

HM 260

Characteristics of nozzles

Measuring the impact or thrust force for determining the discharge velocity and the nozzle efficiency.

Nozzle pressure distribution

HM 261

Nozzle pressure distribution

Measuring the pressure curves in a convergent nozzle and in Laval nozzles.
