Dynamic Simulation in Chemical Engineering


Dynamic simulation is an extension of steady-state process simulation whereby time-dependence is built into the models via derivative terms i.e. accumulation of mass and energy. The advent of dynamic simulation means that the time-dependent description and control of real processes in real or simulated time are possible. This includes the description of starting up and shutting down a plant, changes ... Read More »
