Effect of Froude Number on Submerged Gas Blowing Characteristics. [PDF]

open access: yesMaterials (Basel), 2021
The flow behavior of gas in compressible and incompressible systems was investigated at an ambient temperature in an air–water system and at an operating process temperature in the IronArc system, using computational fluid dynamics. The simulation results were verified by experiments in the air–water system and established empirical equations to enable

Several Problems with Froude-Number Based Scale Modeling of Fires in Small Compartments

open access: yesEnergies, 2019
The Froude-number based reduced-scale modeling is a technique commonly used to investigate the flow of heat and mass in building fires. The root of the method is the thermodynamic model of a flow in a compartment and several non-dimensional flow numbers ...

Smoke Obscuration Measurements in Reduced-Scale Fire Modelling Based on Froude Number Similarity [PDF]

open access: yesSensors, 2019
A common method for investigating various fire- and smoke-related phenoma is a reduced-scale fire modelling that uses the conservation concept of Froude number as its primary similarity criterion.

Prediction of supercavitation shapes for a wide range of Froude numbers

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2022
In this study, we developed an inviscid model to predict the shape of supercavitation in a wide range of Froude numbers (Fr) based on the potential theory suggested by Logvinovich (1973). Visualization experiments were carried out in a cavitation tunnel,

Humans, geometric similarity and the Froude number: is ‘‘reasonably close’’ really close enough? [PDF]

open access: yesBiology Open, 2012
Summary Understanding locomotor energetics is imperative, because energy expended during locomotion, a requisite feature of primate subsistence, is lost to reproduction.

Flow in a waterfall with large Froude number

open access: yesJournal of Computational and Applied Mathematics, 1994
An approximate method is developed to solve the full nonlinear equations governing two-dimensional irrotational flow in the free waterfall, falling under the influence of gravity, at high Froude number based on conditions far upstream. Schwarz-Christoffel transformation is used to map the region, in the complex potential-plane, onto the upper half ...

The Froude number for solitary waves

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 1984
SynopsisThe paper is concerned with the problem of a solitary wave moving with constant form and constant velocity c on the surface of an incompressible, inviscid fluid over a horizontal bottom. The motion is assumed to be two-dimensional and irrotational, and if h is the depth of the fluid at infinity and g the acceleration due to gravity, then the ...

FROUDE VERSUS FROUDE IN FISH LADDER DESIGN [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists), 2018
Hydrodynamic modelling is based on the similitude theory and the dimensional analysis. The complexity of flows in different geometric environments and fluids, requires the use of the similarity criteria in both the construction of a physical model and a ...

FROUDE NUMBER VARIANCE WITH RESPECT TO THE HYDRODYNAMIC RESPONSE OF A NON-STATIC VEHICLE AT A LOW-LYING FLOODED ROADWAY

open access: yesInternational Islamic University Malaysia Engineering Journal, 2021
In terms of stability, the response of static cars in floodwaters has been widely investigated. However, the hydrodynamics of a non-static vehicle exposed to such events are less explored.
