buoyant 2-D blob
Two-dimensional simulation of a buoyant blob.
Computed with the "primitive" equations, meaning a pressure field is calculated that
keeps the flow non-divergent. The isobars of the pressure fluctuation are shown as white contours
in the second pass through the animation.
Third-order upwind advection.
Computation with Python and numpy.
801×801 grid points
- Lots to talk about here, for example: Though vorticity dynamics is not explicitly included in the
model, vorticity dynamics is obeyed. All vorticity is associated with a gradient of buoyancy.
