At the moment, very little knowledge is available about the flow of shear-thinning media in safety valves. In this paper, the flow of aqueous solutions of polyvinylpyrrolidone with a zero-shear viscosity between 0.3 and 3 Pa s in a LESER Type 441 DN

The solubility of triethylene glycol in supercritical methane was measured at temperatures of 298.15 and 316.75 K and pressures up to 9 MPa using a static saturation apparatus with volume displacement. The relative uncertainty of the experimental dat

Two-dimensional phase Doppler anemometer measurements of droplet size and velocity conducted under several nozzle conditions and a systematic variation of the air mass flow quality and liquid phase viscosity show that the air entrainment process is e

The modified Omega method included in ISO/FDIS 4126-10 provides the highest accuracy compared to other modified models frequently used in practice and academia. At the same time, it allows for an exceptionless oversizing of the necessary relief area

The throat-to-stagnation critical pressure ratio for a frictionless and adiabatic nozzle flow of a homogeneous, nonflashing two-phase mixture can only be expressed as the numerical solution of a transcendental equation. A simple, physically plausible

Measurements using two-dimensional Phase Doppler Anemometry as well as high speed cinematography in free jets at several nozzle exit pressures and mass flow rates, show that the Sauter mean droplet diameter decreases with increasing air and liquid-ph

Pressure loaded installations are often protected against overpressure by spring loaded full lift safety valves. Damage to the relief valve itself or to the piping and equipment can result from the so called chattering of the relief valve during disc
