Problems that exhibit multiple time scales arise naturally in many scientific and engineering fields. For transient, distributed process systems, the corresponding models consist of partial differential equations (PDEs), possibly coupled to ordinary differential equations (ODEs) or differential-algebraic equations (DAEs) that describe lumped processes or are used as boundary conditions.
