An implicit particle interaction mechanism is proposed, which can be applied to the problems of colliding particle-jects and particle tracking in turbulent and unsteady flows. The mechanism is based on the idea of virtual particle-grid interactions and provides a linear dependence of the execution time on the number of particles. The scheme was used in conjunction with the random flow-generation procedure to simulate several cases of particle motion inside a continuum medium with different interaction mechanisms.
