Formation of Vortices: Reasons Physical Phenomena Vortices form in fluids due to pressure differences and the conservation of angular momentum, leading to a circular motion as fluid moves toward a drain As water approaches the drain, it accelerates and creates a vacuum, resulting in a centripetal spin that draws water inward The discussion also touches on the misconception regarding Bernoulli's principle, with some members expressing
How does a shear layer make vortices? - Physics Stack Exchange 0 How does a shear layer make vortices? If you have 2 streams of air that are moving at different speeds or opposite directions right beside each other, how does that make a vortex? What causes the rotation, in other words
Are closed streamlines necessary to have vortices? I am studying fluid dynamics, and all the examples I have found so far about vortices show closed streamlines rotating around an axis All these examples suggest that having closed streamlines is a necessary condition to have vortices
How Do Vortices Form in Fluid Dynamics? • Physics Forums Vortices in fluid dynamics are influenced by the Kutta Condition, which addresses the generation of vorticity in flows around sharp edges For incompressible, inviscid fluids, vorticity remains constant, while compressible, viscous fluids can generate vorticity from various sources, such as viscous shear
fluid dynamics - Why do quantum vortices form in superfluids . . . The superfluid can be in a state with zero vortices But if one imparts angular momentum to the superfluid, then the angular momentum is physically expressed either by the superfluid rotating as a whole, or by the presence of vortices In an ordinary fluid vortices can also appear of course, but they get damped away by viscosity
What causes the formation of vortices in a separated flow? Also, I have heard that an inflection point in the velocity profile leads to instability in the flow (i e the flow is unstable to random disturbances) which leads to the production of vortices at higher Re So my question can be split into 2 parts: 1) Why does the velocity gradient lead to vortex formation in the separated flow over a cylinder?
Can a Wing Truly Feel the Effective Airflow? - Physics Forums The discussion centers on whether a wing can truly "feel" effective airflow, which is influenced by downwash and the wing's geometry It is established that the effective airflow experienced by a wing is a result of both freestream airflow and induced airflow due to downwash, which reduces the effective angle of attack Participants argue about the physical implications of induced downwash and
Understanding the Difference Between Vortex and Eddies Hi, I have a small confusion regarding using the terms "vortex and eddy" My doubt is 'what is vortex and eddy?' 'where are this terms appropriate to be used?' 'what is the difference between them?' may be this is silly question but if anyone can help I would thanks him in advance
How do you calculate vortex shedding frequency? 9 I am attempting to try to find out if there is any effect of Von Karman vortices on a group of wind speed readings where it is presumed that due to a mountain nearby the data collection spot Von Karman vortices were formed which would register in the data
