Three modular cylindrical vessel configurations are available for the sloshing experiments including the well known flat bottom geometry illustrated in the Figure below on the left, the concave bottom geometry illustrated in the middle and the convex bottom geometry illustrated on the right.more...

Imagine you are just sitting at your desk having a cup of coffee in front of you. When you are now moving the cup carefully back and forth then you will recognize that the free surface of your coffee is no longer horizontal but it is oscillating up and down perpendicular to the excitation direction. This is called lateral sloshing.more...

Liquid sloshing represents an undesired effect concerning most applications for propellant storage in space transportation vehicles. According to gravity dominated free surface flows in propellant vessels even small vibrations can cause enormous liquid motion inside rocket tanks. The understanding of sloshing is of particular importance, since cryogenic propellant is utilized to power space vehicles, such as the planned ESC-B upper stage from Ariane 5 launcher.more...
