VORTICITY IN FLOW FIELDS in relation to Prandtl’s work and subsequent developments

چکیده
One of the important properties of boundary layer is, from the point of view of Strömungslehre, that it pumps vorticity into the flow field. Vorticity in fluid flows plays diverse roles and produces tremendous variety of flow phenomena. We consider four aspects of vorticity in fluid flows: (A) Kinematical aspect of a vortex sheet, (B) mechanical aspect of hydrodynamic impulse of a vortex system, (C) dynamical aspect: vorticity dynamics, excitation of acoustic waves and formation of dissipative structure in turbulence, and (D) gauge field associated with local rotational symmetry.

EXISTENCE OF A STEADY FLOW WITH A BOUNDED VORTEX IN AN UNBOUNDED DOMAIN
We prove the existence of steady 2-dimensional flows, containing a bounded vortex, and approaching a uniform flow at infinity. The data prescribed is the rearrangement class of the vorticity field. The corresponding stream function satisfies a semilinear elliptic partial differential equation. The result is proved by maximizing the kinetic energy over all flows whose vorticity fields are rearra...
متن کاملAnalysis of Some Singular Solutions in Fluid Dynamics
Studies on singular flows in which either the velocity fields or the vorticity fields change dramatically on small regions are of considerable interests in both the mathematical theory and applications. Important examples of such flows include supersonic shock waves, boundary layers, and motions of vortex sheets, whose studies pose many outstanding challenges in both theoretical and numerical a...
متن کاملNumerical simulation of flow hydrodynamic around dolphin body in viscous fluid
The biomimetic and hydrodynamic study of aquatic animals is one of the most challenging computational fluid dynamics topics in recent studies due to the complexity of body geometry and the type of flow field. The movement of the aquatic body, and particularly the tail section and the corresponding movement of fluid around the body, causes an unsteady flow and requires a comprehensive study of t...
متن کاملDepletion of nonlinearity in magnetohydrodynamic turbulence: Insights from analysis and simulations.
It is shown how suitably scaled, order-m moments, D_{m}^{±}, of the Elsässer vorticity fields in three-dimensional magnetohydrodynamics (MHD) can be used to identify three possible regimes for solutions of the MHD equations with magnetic Prandtl number P_{M}=1. These vorticity fields are defined by ω^{±}=curlz^{±}=ω±j, where z^{±} are Elsässer variables, and where ω and j are, respectively, the...
متن کاملComparison of three different numerical schemes for 2D steady incompressible lid-driven cavity flow
In this study, a numerical solution of 2D steady incompressible lid-driven cavity flow is presented. Three different numerical schemes were employed to make a comparison on the practicality of the methods. An alternating direction implicit scheme for the vorticity-stream function formulation, explicit and implicit schemes for the primitive variable formulation of governing Navier-Stokes equatio...
