Abstract

Consideration is given to a model intended for examining open flows in general, including transition mechanisms by incorporating physical factors essential to turbulent behavior while retaining simplicity to enable detailed analysis. All unforced solutions of the model are nonchaotic. With periodic forcing, the model is receptive to certain frequencies or frequency bands.
