WebThe Euler number (Eu) is a dimensionless number used in fluid flow calculations. It expresses the relationship between a local pressure drop caused by a restriction and the kinetic energy per volume of the flow, and is used to characterize energy losses in the flow, where a perfect frictionless flow corresponds to an Euler number of 0. The inverse of the … WebApr 11, 2024 · 1. Introduction. The pioneering work of Morton, Taylor & Turner (Reference Morton, Taylor and Turner 1956) established the basic equations governing the rise of buoyant plumes, jets and thermals.Asymptotic solutions were found for flows from point sources in stably and neutrally stratified environments, with dimensional reasoning …
WebApart from the anisotropy and inhomogeneity of the flow, insufficiently high Rayleigh numbers, and intermittency corrections (which all hinder the identification of such a potential regime), there are also reasons, as a matter of principle, why such a scaling regime may be limited to at most a decade, namely the lack of clear scale separation … WebFluid mechanics Similitude has been well documented for a large number of engineering problems and is the basis of many textbook formulas and dimensionless …
