Abstract:
We analysed a high-fidelity DNS dataset of accelerating flow through a porous medium consisting of uniform spheres in hexagonal close-packed arrangement. The fluid was accelerated from rest by a constant pressure gradient until the superficial volume-averaged velocity attained its steady-state amplitude. Our focus is on the generation mechanism of the overshoot of the superficial streamwise velocity that appears just before the steady-state amplitude is reached. The relative magnitude of the vel...     »
