A Two-Dimensional Free Surface and Bubble Dynamics Code
2DynaFS© is a computer program for studying bubble dynamics in situations for which the assumption of axisymmetry can be made. This program can handle the dynamics of single or multiple bubbles in an infinite liquid medium, near a free surface, near a “globule” or a “cell”, near an axisymmetric rigid and responding body, near a finite plate, and near an infinite wall (i.e. in a half-space). The following physical effects can be included in the analysis; 1. Gravitational forces along the axis of symmetry 2. Various bubble/cell contents and interface laws 3. An optional external flow field e.g. a line vortex (Rankine and Lamb models) or a user provided axisymmetric flow field 4. Multiple bubbles and bodies 5. Polytropic gas law for the non-condensable gas inside the bubble 6. A free surface Because the physical problem is discretized only in the meridional plane and azimuthal effects are analytically integrated, the code is very efficient for studying axisymmetric fluid flow in the presence of large free surface deformations. Additional configurations required by customers can be added upon request. Dynaflow, Inc.® can also customize the program through mutual arrangement. |
