15.12.6 Interphase Exchange During Stochastic Tracking

When stochastic tracking is performed, the interphase exchange terms, computed via Equations  15.12-1 to  15.12-8, are computed for each stochastic trajectory with the particle mass flow rate, $\dot{m}_{p0}$, divided by the number of stochastic tracks computed. This implies that an equal mass flow of particles follows each stochastic trajectory.
