Gas Distribution in Pump
The efficiency of pumps decreases drastically if gas is sucked in with the liquid.
This project dealt with pumps that are bound to suck gas in. The question is where the gas is
concentrated and how the pumping efficiency can be ensured.
The geometry is shown in the first picture together with the pressure distribution
within the blade channels. The animation shows the distribution of gas concentration as it changes with time.
Colours:
Red = High concentration
Blue = Low concentration

Centrifugal Separators
Centrifugal forces are often applied to separate dirt (particles or droplets) from a carrier medium.
The question is where should the outlet be to obtain the highest purity.
The first animation shows the rotation of a drum initially partially filled with liquid. The colours
show the pressure distribution within the liquid. Hot colours represent a high pressure. Cold colours
indicate low pressures.
A separating instrument is installed within the drum which carries the purified liquid out of the
separator in a direction perpendicular to the animation plane.
