Cyclic flow deposition
WebDec 2, 2024 · Facies produced by deposition on submarine cyclic step. Flow along the lee-side of the bedform is supercritical and erosive while flow along the stoss side is subcritical and depositional (modified after Postma & Cartigny, 2014 ). WebNov 5, 2015 · Hence, it is possible to extrapolate steady state flow deposition results from cyclic flow condition. Kleinstreuer and Zhang determined the air-particle streams in locally occluded G3–G6 airways using the same quasi-steady approach. In this study, under the quasi-steady assumption for blocked airways, matching Reynolds numbers of 463, 932 …
