WebAug 15, 2024 · 3.1. Flow past a sphere at R e = 200. The steady state behaviour of a neutrally stratified flow past a sphere at the Reynolds numbers between 20 and 210 is characterised by the axisymmetric flow in the wake region. It is well studied by means of direct numerical simulations [1] and verifiable by experimental observations [52].

WebApr 16, 2024 · These authors show, for instance, that spherical shapes for Reynolds numbers of about 100 or higher are found for sufficiently small Eötvös and Morton numbers. Below, we develop and test a new expression for Cd applicable to spherical particles. WebThe scheme of the flow past a sphere at intermediate Froude and Reynolds numbers is close to a rectangular form. A transverse cross-sectional view of the density wake is shown in Figure 21 . The position of the long side depends on the value of the Froude number (or velocity for a constant body diameter).
