Abstract

There are some numerical simulation data of liquid flow in different construction tanks. Bundled software FlowVision is used. Are shown that it is necessary to include surface tension and wettability in mathematical model; it is necessary to ensure smooth acceleration from zero to known value, there is no set known value of acceleration and liquid level at the beginning of numerical simulation.

Keywords:

liquid tank, numerical simulation, free surface, surface tension.
