Multiphase simulation of droplet dynamics by smoothed particle hydrodynamics method

In this work, simulating multiphase flows by implementing smoothed particle hydrodynamics (SPH) as a mesh-free method is presented. The formulation is validated on test cases including droplet evolution, droplet coalescence and droplet splashing by taking surface tension force into account while a high density ratio exists between fluids. Results are presented for time variation of each object at variation intervals until equilibrium condition is approached
