Minimum Flow Estimated By the Froude Number
Impacts of Global Climate Change, 2005Following the development and management of water resources to satisfy the human demand, the quantity and quality of flow in streams change in both space and time. With increasing recognition of streams being fundamental to human existence, concerns for the effect on the stream ecosystem have been raised by government, biologists and private citizen ...

Oblique liquid curtains with a large Froude number
Journal of Fluid Mechanics, 2018This paper examines two-dimensional liquid curtains ejected at an angle to the horizontal and affected by gravity and surface tension. The flow in the curtain is, generally, sheared. The Froude number based on the injection velocity and the outlet’s width is assumed large; as a result, the streamwise scale of the curtain exceeds its thickness. A set of

Froude number paradoxes in modeling of snowdrift
Journal of Wind Engineering and Industrial Aerodynamics, 1990Abstract It is well known that Froude scaling is not always suitable for the modeling of snow drifting. However, the reason of the unsuitability has not been revealed. This paper presents three paradoxes which prove unsuitability of the Froude number as the similitude parameter in the modeling of snowdrift.

Froude-Zahl Fr (Froude number Fr)
2000Es handelt sich um eine dimensionslose Kennzahl im Sinne der Dimensionsanalysis, die im Zusammenhang mit der Wirkung der Schwerkraft auftritt. Damit ist sie bei thermischen Auftriebsstromungen relevant. In diesem Zusammenhang geht sie jedoch in den meisten Fallen formal in anderen Kenn-zahlen auf, tritt also nicht explizit in Erscheinung.

Nonlinear Ship Waves at Low Froude Number
Journal of Ship Research, 1988The wave pattern of a thick ship-like object with finite bow and stern angles 0 <β<π/2 is studied. The completely blunt form p = π/2 is excluded. It turns out that the wave pattern is strongly influenced by the nonlinear terms at the free surface. The wave pattern is determined by means of the ray method.

Roll Motion of Yachts At Zero Froude Number
The International Journal of Small Craft Technology, 2004Yachts tend to roll uncomfortably whilst at anchor, causing discomfort to the crew and passengers, generating stresses on equipment, and making operations such as embarking and disembarking hazardous activities. A research program is under way to better understand the design factors and environmental influences leading to the rolling problem, with a ...

Effect of the Froude number on assessment of the bridge afflux
Proceedings of the Institution of Civil Engineers - Water Management, 2008This paper presents the findings of laboratory model testing of arch and straight-deck bridge constrictions, in a symmetrical compound channel flume having different roughness conditions. Four different types of bridge models, namely a single-opening, semicircular arch bridge, a multiple-opening, semicircular arch bridge, a single opening, elliptic ...

Froude Number Scaling of Wind-Stress Coefficients
Journal of the Atmospheric Sciences, 1969Abstract Following the verification of the logarithmic nature of the wind profile and the establishment of a non-dimensional expression relating the shear velocity and surface roughness, a Froude number is proposed for scaling the wind stress at the air-water interface. A correlation curve for wind stresses determined at all fetches is presented and is
