This paper presents open challenges and perspectives of propellant management for
crewed deep space exploration. The most promising propellants are liquid hydrogen and …

This effort investigates advancing cavitation modeling relevant to computational fluid
dynamics (CFD) through two strategies. The first aims to reformulate the cavitation models …

This paper presents an experimental investigation on the fluid hammer phenomenon
generated when filling a pipe line under vacuum conditions with a closed end. This physical …

The motion of liquid filling a pipeline is impeded when the gas ahead of it cannot escape.
Entrapped gas will lead to a significant pressure build-up in front of the liquid column, which …

Experimental work was performed to measure the priming event pressure transient levels in
unrestricted liquid propulsion system tubing. An existing water hammer experimental setup …

The objective of this research is to investigate the velocity of oil drops within the impeller of
an electrical submersible pump (ESP) working with oil-in-water dispersion flows at different …

High pressures and high temperatures may arise in pipelines when a liquid column is
suddenly accelerated into a gas pocket trapped at a closed end. A mass oscillation occurs …

When a pressurized liquid enters a pipeline with a closed end and under vacuum
conditions, the resulting liquid front suddenly is brought to rest at the end of the pipe. This …

An experimental study was conducted to evaluate pressure transient levels in unrestricted
and restricted liquid monopropellant propulsion system configurations and propellant …
