Resumo(s)
Liquid cryogenic propellants are at the forefront of space
propulsion due to their optimal trade-off between
performance and weight (Sutton et al. 2017). As a result,
investigations on the sloshing dynamics of such fuels have
been carried out since the early 1960s. Sloshing, defined as
the movement of the free liquid surface within a reservoir
(Abramson, 1966), induces two types of undesirable effects:
(a) displacement of fuel tank’s centre of mass, which disturbs
the stability and manoeuvrability of the spacecraft; (b)
thermal mixing between the pressurised ullage and subcooled
liquid, which can generate large fluctuations in the tank
pressure, leading to structural instabilities and thrust
oscillations in the propulsive system. [...]
