A nozzle is a passive mechanical device that connects two reservoirs at different pressures, and whose profile must allow a reversible adiabatic flow (at least theoretically). Its profile must ...

The investigation of critical flow model for supercritical pressure condition is relatively rare. Based on isentropic flow and thermal equilibrium assumptions, a model is derived to calculate ...

The study of the isentropic one-dimensional flow of a perfect gas leads to the notion of nozzle flow, which is found in many thermal machines. In this case, by considering the pipe as fixed (or ...

a small symbolic/numeric playground for quasi-1D isentropic nozzle flow. This version is intended as a compact teaching and exploration tool for: students learning compressible flow; engineers who ...

NiceProp is an object-oriented Python program for teaching and research in the field of Non-Ideal Compressible Fluid Dynamics (NICFD). NiceProp is used to investigate and characterize the flow ...

Mathematical modeling demonstrates that nozzle distribution on drillbits affects the performance of the drilling fluid flow from the bit. This article is about the internal flow of nozzles on a rotary ...

This article will present the sizing technique for two-phase flow through relief valves and orifices. The procedure is simple but rigorous and generally applicable. The technique requires solving the ...

In order to correctly size pressure relief valves (PRVs), a robust understanding of discharge coefficients for vapor, liquid and two-phase flow is crucial A pressure relief valve (PRV) is used to ...
