Astley, R.J. and Cummings, A. (1995) Wave propagation in catalytic converters: Formulation of the problem and finite element solution. Journal of Sound and Vibration, 188 (5), 635-657. (doi:10.1006/jsvi.1995.0616).

Abstract

The fluid-dynamical equations governing wave propagation in catalytic converter elements containing isothermal mean flow are linearized, approximated and written in appropriate forms to act as the basis for a finite element solution scheme involving time harmonic variation. This solution scheme is described and numerical results are presented and compared—where possible—to other published data; favourable agreement is noted.
