Vortex motion in wall-bounded viscous flow

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1985
Abstract The flow field of a vortex in a viscous shear flow is found by constructing a uniformly valid asymptotic expansion consisting of an inner solution field represented, to lowest order, by a two-dimensional, nonlinear, inviscid Stuart vortex and an outer solution field represented, to lowest order, by either a two-dimensional ...

Visualizing Vortex Shedding of an Elastic Plate Interacting with a 3D Viscous Flow

2009 Ninth IEEE International Conference on Computer and Information Technology, 2009
Fluid-flexible-structure-interaction is a challenging problem in fluid dynamics that is not well understood, due to the highly complicated nature of the problem. Vortex motion plays a central role in such interaction. In this paper we visualize the vortex shedding from a flexible plate tethered at its midline in a viscous incompressible flow in three ...

Vortex dynamics of viscous fluid flows. Part 1. Two-dimensional flows

Journal of Fluid Mechanics, 1994
The method of product integration is applied to the vortex dynamics of two-dimensional incompressible viscous media. In the cases of both unbounded and bounded flows under the no-slip boundary condition, the analytic solutions of the Cauchy problem are obtained for the Helmholtz equation in the form of linear and nonlinear product integrals.

Two-dimensional viscous vortex flow around a circular cylinder

Aerospace Science and Technology, 2001
Summary: We develop a code based on vortex method for simulating viscous vortex flow around a circular cylinder. An original method to obtain no-through and no-slip condition is described in detail. The diffusive part of vorticity transport equation is treated using a deterministic method based on the solution of heat equation.

The Vortex Pump Under Highly Viscous Liquid Flow Conditions

Arabian Journal for Science and Engineering, 2018
The hydraulic performance and flow patterns in a standard motor-connected vortex pump with a specific speed of 76 are tackled by using CFD method under water and highly viscous oil flow conditions. The variations in performance curve and hydraulic loss caused from increased liquid viscosity are clarified; the flow rate, head and efficiency correction ...

Vortex Structure Around the Cylinder at a Flow of Viscous Fluid

2014
The problem of a stationary viscous incompressible fluid flow around the cylinder has been analyzed by means of the asymptotic methods. The fluid flow equations in the variables “stream function-a vortex” are considered. One component of a vortex vector has remained in case of two-dimensional motion.
