用户手册里是这样说的:
The Aspen HYSYS dynamic model shares the same physical property packages as the steady state model. The dynamic model simulates the thermal, equilibrium, and reactive behavior of the chemical system in a similar manner as the steady state model.
On the other hand, the dynamic model uses a different set of conservation equations which account for changes occurring over time. The equations for material, energy, and composition balances include an additional “accumulation” term which is differentiated with respect to time. |
