Numerical Simulation on Collision Behaviors of Binary Aluminum Droplets Based on Phase Field-lattice Boltzmann Method
Phase field-Lattice Boltzmann method is used in this work to research the collision behaviors of binary Aluminum droplets with B=0.06 and We=15～190.Behaviors of coalescence after substantial deformation and reflexive separation producing satellite droplets are captured.The critical We marking the transition from coalescence to separation obtained from simulation are compared with the results derived from two types of analysis model for separation prediction,which shows that the prediction values of model omitting viscosity of droplets fit better with the value of simulation results compared with its counterpart considering viscosity,on account of the significantly low viscosity of Aluminum droplets.
