- Abstract
- This report is an investigation on how well fuel sloshing in a rotating cylindrical
tank can be modeled numerically. The investigation is motivated by the
need to understand the fuel sloshing in the new Ariane 6 rocket developed by
the European Space Agency. Two cases are studied, the lled tank and the
half lled tank at Reynolds numbers of 71000-212000. The softwares studied are
FINE/Open with OpenLabs from Numeca and DrNUM from enGits. For the
lled tank, the softwares are able to capture the main characteristics of the
ow
development such as the rotational velocities and a secondary
ow developed during
spin-up which is known as the Ekman pumping. The time to reach a solid
body rotating is investigated and compared with... (More) - This report is an investigation on how well fuel sloshing in a rotating cylindrical

body rotating is investigated and compared with experimental and theoretical
data. The comparison showed that the spin-up time is not predicted correctly.
The free surface of a half lled tank introduces a lot of instabilities and numerically
diculties. Stable simulations are achieved but no solid body rotation is
reached. (Less) - Popular Abstract (Swedish)
- Lunds Tekniska högskola samarbetar med European Space Agency för att undersöka möjligheten att simulera hur bränslet i en rackettank rör sig. Resultaten av undersökningen visar att det finns möjligheter att bespara miljonbelopp på dyra rymdexperiment genom att testa samma experiment under simulerade rymdförhållanden här på jorden. Kunskapen av dessa simuleringar kan göra morgondagens raketer både billigare och säkrare.
