Humans, geometric similarity and the Froude number: is ‘‘reasonably close’’ really close enough? [PDF]
Biology Open, 2012 Summary Understanding locomotor energetics is imperative, because energy expended during locomotion, a requisite feature of primate subsistence, is lost to reproduction.

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

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

Prediction of supercavitation shapes for a wide range of Froude numbers
International 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,

Vortex ring refraction at large Froude numbers [PDF]
Physical Review E, 2010 We have experimentally studied the impact of an initially planar axisymmetric vortex ring, incident at an oblique angle, upon a gravity-induced interface separating two fluids of differing densities.

Journal of Hydraulic Engineering, 1985 A Froude number that is applicable to subdivisions of a cross section is developed assuming one-dimensional flow. The subdivision Froude number is shown to determine accurately the flow regime in subdivisions of a cross section. An imaginary subdivision Froude number in a floodplain indicates that the velocity is increasing with depth and that a one ...

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

Large eddy simulation on the wake characteristics of linearly stratified flow past a sphere [PDF]
Scientific ReportsIn this study, Large Eddy Simulation (LES) has been employed to examine the influence of the Froude number (Fr) on the linearly stratified wake and internal waves behind a sphere at a subcritical Reynolds number of Re = 3700.

Numerical Analysis of Resistance Characteristics of a Novel High-Speed Quadramaran
Polish Maritime Research, 2023 This paper utilised computational fluid dynamics (CFD) technology to calculate the resistance of a novel high-speed quadramaran in calm water using the Navier‒Stokes (N‒S) equation, analysed the total resistance, frictional resistance, and residual ...

Mach and Froude Numbers on Mars [PDF]
The Planetary Science Journal, 2022 Abstract Mars atmospheric global circulation models exhibit transonic jet streaks during northern winter, which motivates this study of the Mach number, Ma (the ratio of flow speed to the speed of sound), and Froude number, Fr (the ratio of flow speed to the speed of buoyancy waves), as a function of season and location.
