An investigation of the flow structure beneath solitary waves with constant vorticity on a conducting fluid under normal electric fields [PDF]
, 2023 The motion of an interface separating two fluids under the effect of electric fields is a subject that has picked the attention of researchers from different areas. While there is an abundance of studies investigating the free surface wave properties, very few works have examined the associated velocity field within the bulk of the fluid. Therefore, in

On the Circulation and the Position of the Forward Stagnation Point on Airfoils [PDF]
International Journal of Mechanical Engineering Education, 2007 Lift and velocity circulation around airfoils are two aspects of the same phenomenon when airfoils are not stalled and the Kutta—Joukowski theorem applies. This theorem establishes a linear dependence between lift and circulation, which breaks when stalling occurs. As the angle of attack increases beyond this point, the circulation vanishes. Since the

Analysis on the steady Euler flows with stagnation points in an infinitely long nozzle [PDF]
arXiv, 2022 A recent prominent result asserts that steady incompressible Euler flows strictly away from stagnation in a two-dimensional infinitely long strip must be shear flows. On the other hand, flows with stagnation points, very challenging in analysis, are interesting and important phenomenon in fluids.

Solitary waves on flows with an exponentially sheared current and stagnation points [PDF]
arXiv, 2022 While several articles have been written on water waves on flows with constant vorticity, little is known about the extent to which a nonconstant vorticity affects the flow structure, such as the appearance of stagnation points. In order to shed light on this topic, we investigate in detail the flow beneath solitary waves propagating on an ...

Richardson's pair diffusion and the stagnation point structure of turbulence [PDF]
, 2002 DNS and laboratory experiments show that the spatial distribution of straining stagnation points in homogeneous isotropic 3D turbulence has a fractal structure with dimension D_s = 2. In Kinematic Simulations the time exponent gamma in Richardson's law and the fractal dimension D_s are related by gamma = 6/D_s. The Richardson constant is found to be an
