64th ESA Parabolic Flight Campaign Bulletin Board
The von Karman Institute is ready to participate to the 64th ESA Parabolic Flight Campaign which will take place from the 26th to the 29th April 2016.
The objectives of the VKI experiment is to determine both the liquid/gas interface shape and the fluid velocity during sloshing in a small cylindrical closed reservoir. During the parabolic flight test campaign the accelerations generated by the parabolic maneuver itself, will be used as trigger for a sloshing wave that will be therefore characterized.
This experiments at zero G was possible thanks to the contribution of ESA and BELSPO.

The motion of a free liquid surface inside its container is called sloshing and is strongly affected by the external excitations applied to the container. You may experience sloshing while walking with a cup of coffee in your hand with the inevitable consequent spilt.
The understanding and the prediction of this particular motion are extremely important in many fields. Indeed, the motion of liquids inside containers can refer to embarked tanks filled of fluid, motion of cooling liquids in systems subjected to earthquake or motion of propellant into reservoirs. The latter can influence the dynamic stability and performance of a vehicle, be it a ship, a missile, a rocket or a satellite.
