A RANDOM PARTICLE METHOD BASED ON A KINET IC-EQUATION FOR THE NUMERICAL-SIMULATION OF DENSE SPRAYS OF LIQUID DROPLETS

We propose in this Note, a kinetic equation which takes into account c ollisions occuring in a dense spray of liquid droplets carried by a ga z flow. Our model relies on the assumption that a collision results ei ther in elastic rebound or in coalescence. The collision operator is p roved to have similar properties to that of Boltzmann. This analogy al lows us to use the ideas of Babovski (see [1]) for the construction of a random particular method to discretize the kinetic equation.
