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

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.

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,

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 ...

Physical modeling of a fire with the use of the Froude number
Budownictwo i Architektura, 2019 Ever since the field of Fire Safety Engineering first came into existence, small-scale (model scale) fire tests were the source of much valuable information about the phenomena occurring during combustion. Over the years, several computational methods to

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.

Inviscid, zero Froude number limit of the viscous shallow water system
Open Mathematics, 2021 In this paper, we study the inviscid and zero Froude number limits of the viscous shallow water system. We prove that the limit system is represented by the incompressible Euler equations on the whole space.

Experimental analysis of hydraulic jump at high froude numbers [PDF]
Sādhanā, 2021 Abstract The hydraulic jump is a rapid transition state from supercritical to subcritical flow that occurs commonly in rivers, prismatic channels and downstream of spillways. In this study, the characteristics of the hydraulic jump in a stilling basin downstream of the spillway chute channel with the slopes of α = 12o and 30o were investigated ...
