In addition to the logic of what happens when system events occur, discrete event simulations include the following: • Priority queue, • Animation event handler, and • Time re-normalization handler (as simulation runs, time variables lose precision. After a while all time variables should be re-normalized by subtracting the last processed event time). Webprecision and subsequently the two-phase flow was simulated. Multiple monitors for pressure, velocity and particle concentration were used to judge convergence of the two phase flow. The boundary conditions for each model are summarised in Table 3. Discrete Phase Model The particle properties for each phase are also shown in Table 3.
