Supercritical flow - Wikipedia
A supercritical flow is a flow whose velocity is larger than the wave velocity. [clarification needed] The analogous condition in gas dynamics is supersonic speed.
Conditions for Critical, Subcritical and Supercritical Flow
If the Froude Number is greater than one then it will be supercritical flow with the depth of flow less than critical depth and flow velocity greater than critical velocity. A hydraulic jump will occur in order to make the transition from supercritical flow to subcritical flow.
Supercritical Flow - an overview | ScienceDirect Topics
Critical and Supercritical Flow. Critical velocity in water flow is any faster than the maximum wave speed, so it is analogous to supersonic velocity in a gas. A Froude number (Fr) of greater than 1 is associated with supercritical flow.
2003年3月24日 · We can find the point of minimum energy on each specific energy curve for a given q. Solving, we find the depth at which the minimum specific energy occurs. This depth is called the critical depth, d . : The flow is subcritical. d < d : The flow is supercritical. The wave speed c is called the wave celerity.
Supercritical flow - (Intro to Civil Engineering) - Fiveable
Supercritical flow is characterized by a higher velocity than wave speed, resulting in a Froude number greater than 1, while subcritical flow has a velocity less than wave speed with a Froude number less than 1.
Sub-Critical and Super-Critical Flow - University of Texas at Austin
Hence, if then the stream's flow velocity falls below the wave speed--such flow is termed sub-critical. On the other hand, if then the flow velocity exceeds the wave speed--such flow is termed super-critical.
Flow Profiles - Oregon State University
Supercritical flow is dominated by inertial forces and behaves as rapid or unstable flow. Supercritical flow transitions to subcritical through a hydraulic jump which represents a high energy loss with erosive potential.
Basic Hydraulics 2: Critical Flow — The Science of Rivers
2020年3月30日 · The faster the water, the narrower the “V.” Scientists call this condition “supercritical flow.” And as you might have guessed by now, if the current is moving slower than the critical velocity, this is called “sub critical flow.” The significance of …
Supercritical Flow | Dynamics, Applications & Analysis
2024年5月26日 · Supercritical flow, a concept critical in fluid dynamics, refers to the state of a fluid beyond its critical point, where distinct liquid and gas phases do not exist. This phenomenon is of particular interest in various fields, ranging from engineering to environmental science.
Hence, in this course, the parameter called specific energy will first be used to introduce the concepts of critical, subcritical, and supercritical flow. Various calculations related to critical, subcritical and supercritical flow conditions will be presented, including …
