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.
Flow of compressible fluids
Subsonic and sonic flow through different measuring objects.
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
Measuring the impact or thrust force for determining the discharge velocity and the nozzle efficiency.
Nozzle pressure distribution
Measuring the pressure curves in a convergent nozzle and in Laval nozzles.
