Flow through perforated plates
WebDirect numerical simulations of the Darcy and non-Darcy flows through plates with circular holes are carried out at the pore scale. With a view to evaluating the linear (or Darcy drag) and non-linear drag (or Forchheimer drag) of perforated plates, the dependence of pressure drop on the transpiration velocity is first discussed for a porosity of 0.1∼0.4 and … WebFeb 22, 2024 · To control these processes, perforation of the CS (a large number of through holes) can be used. The article considers the flow around continuous and perforated plates, accompanied by the appearance, transformation and interaction of complex vortex structures at angles of attack up to 90 °.
