Numerical Solutions of the Navier Stokes Equations for Incompressible Uniform Flow Past a Parabola


Book Description

Numerical solutions are obtained to the Navier-Stokes equations for the problem of flow past a parabolic cylinder in an infinite stream. The boundary conditions at infinity have been applied at finite distances and the effects studied and compared with recent works. It was found that finite boundaries had small, but noticeable effects on the wall shear, and more marked influence on the internal flow structure. (Author).
















Numerical Solution of the Incompressible, Two-dimensional, Time-dependent Navier-stokes Equations for a Body Oscillating in Pitch in a Moving Fluid


Book Description

A numerical solution of the incompressible, two-dimensional, time-dependent Navier-Stokes equations, which is implicit in time as well as space, has been developed for the case of a uniform flow past a body with rectangular boundaries undergoing pitch oscillations. The Navier-Stokes equations are written in the form of the vorticity equation and the Poisson equation for the stream function, thus using the vorticity and stream function as dependent variables, rather than the velocity components and the pressure. The equations are written in a moving coordinate system fixed with respect to the oscillating body, which undergoes pitch oscillations about an arbitrary axis. (Author).




Numerical Solution of the Incompressible Navier-Stokes Equations


Book Description

This book presents different formulations of the equations governing incompressible viscous flows, in the form needed for developing numerical solution procedures. The conditions required to satisfy the no-slip boundary conditions in the various formulations are discussed in detail. Rather than focussing on a particular spatial discretization method, the text provides a unitary view of several methods currently in use for the numerical solution of incompressible Navier-Stokes equations, using either finite differences, finite elements or spectral approximations. For each formulation, a complete statement of the mathematical problem is provided, comprising the various boundary, possibly integral, and initial conditions, suitable for any theoretical and/or computational development of the governing equations. The text is suitable for courses in fluid mechanics and computational fluid dynamics. It covers that part of the subject matter dealing with the equations for incompressible viscous flows and their determination by means of numerical methods. A substantial portion of the book contains new results and unpublished material.
