Kármán vortex street
It is a physical phenomena that occur in the fluid flow in the duct with an obstacle. Particles flowing around obstacle create interesting shapes which depend on the Reynolds number. The duct is full of fluid. See picture on left - colors decode velocity components in the simulation domain and massless tracers are white. Simulation method: SIMPLE (my code is available here). Picture source: my MSc Thesis.
Multiphase Flows
If two fluids of various physical and chemical properties are mixed together, due to internal forces that acts between phases various, interesting phenomena occur. Here I present the simulation of multiphase droplet formation was done using the Lattice Boltzmann Method and Shen-Chen multiphase model. Codes are available on my website. Animated version is available on my YouTube channel.
