In this paper, we explore the stability and dynamical relevance of a wide variety steady, time-periodic, quasiperiodic, chaotic flows arising between orthogonally stretching parallel plates. We first all steady flow solution families formerly identified by Ayats et al. [“Flows plates,” Phys. Fluids 33, 024103 (2021)], concluding that only one originates from Stokesian approximation is actually ...
