WebMar 10, 2024 · The behavior of neutrally buoyant, non-Brownian suspensions subject to square-wave flow oscillations in Hele-Shaw cells is investigated experimentally. The velocity field across the cell gap is determined by tracking particles in a plane parallel to the main flow. The suspension develops an instability characterized by the growth of a … WebApr 14, 2024 · ANSYS Fluent was employed to simulate the processing flow field characteristics for different lengths of oscillation cavities. The simulation results indicate that the velocity of the jet shaft reached a maximum of 178.26 m/s when the length of the oscillation cavity was 4 mm. The erosion rate of the material is linear with the …
WebHigh frequency oscillatory ventilation, or HFOV, differs from conventional ventilation in that instead of delivering a set number of breaths at a certain pressure or volume, HFOV provides volumes equal to or less than the anatomical dead space using respiratory rates with a range of 3 to 15 Hertz which is also 3 to 15 cycles per second. A boundary layer can transition to turbulence through a number of paths. Which path is realized physically depends on the initial conditions such as initial disturbance amplitude and surface roughness. The level of understanding of each phase varies greatly, from near complete understanding of primary mode growth to a near-complete lack of understanding of bypass mechanisms.
