Lec-18: Unsteady & oscillatory flows || order-of-magnitude analysis

0:00 - Semi-infinite unbounded shear flow

18:50 - Oscillatory pseudo steady-state bounded flow

36:07 - Fast oscillation regime

45:55 - Pulsatile pressure-driven flow

note: at 1:01:00 min mark (end of lecture) I'm showing only the oscillatory component of the flow for better visualization. This solution for arbitrary Strouhal number is out of the syllabus for 2025 che611
