The ability to separate liquid and gas phases in the absence of a gravitational acceleration has proven a challenge to engineers since the inception of space exploration. Due to our singular experience with terrestrial systems, artificial body forces

The accurate prediction of the mechanical and thermodynamic behavior of cryogenic liquids in tanks of liquid propelled rocket stages is critical for the design of the tank layout, the pressurization system, and the control algorithm. To analyse the b

The surface evolver (SE) algorithm is a valued numerical tool for computations of complex equilibrium interfacial phenomena. In this work, an iterative procedure is implemented such that SE can be employed to predict steady-state flows along capillar

This paper is concerned with steady and unsteady flow rate limitations in open capillary channels under low-gravity conditions. Capillary channels are widely used in Space technology for liquid transportation and positioning, e.g. in fuel tanks and l

In low gravity flight phases without main thrust activations, the liquid tends to wet or migrate along the walls or interior structures within the spacecraft tanks. In many cases a combination of buoyancy effects, e.g. during RCS firing, and capillar
