Drip Simulation
Infatuated with the world of computational fluid dynamics (CFD) after taking a class on it, I was eager to try some simulations of interest in my own time. I didn’t have the opportunity prior to work with 2-phase simulations and I was interested in droplet deformation after seeing a similar simulation. This sim shows a small droplet of water falling through air into a pool to visualize the resulting splash and ripple physics (left). An afterthought of the resulting data was to visualize the air movement around the droplet as it falls. The resulting vortex shedding off the droplet could also be seen in terms of the y-velocity of the air (right). The calculation times were optimized by implementing a dynamic mesh which refines based on phase gradients between water and air. (Given, it still took a day or two because it liked to crash the simulation overnight…oh well.)
