This book was released on 1988 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The liquid flowfield in a full or partially-filled right circular cylinder in rapid axial rotation is investigated numerically. The governing equations ar the axisymmetric, unsteady, viscous, incompressible Navier-Stokes equations. These equations are written in stream function-vorticity form for a cylindrical coordinate system in a nonrotating reference frame. The governing equations are discretized using second-order finite-differences for time and space on a nonuniform grid employing logarithmic stretching in regions where high flow gradients are anticipated. Time dependent solutions for Reynolds numbers between 1,000 and 100,000 have been obtained using a Gauss-Seidel relaxation procedure. For partially filled cases the free surface is assumed to be cylindrical and located at a constant radius from the axis of spin. Numerical solutions for full cylinders are consistent with previous solutions and experimental data. Numerical solutions for a partially-filled cylinder are consistent with experimental data for a liquid centrifuge except at the free surface. Computations of the roll moment exerted on the cylinder by the contained liquid shows a smaller moment for the partially-filled compared with the full cylinder results. Keywords: Finite difference, Incompressible flow, Liquid filled projectile, Liquid moment, Unsteady flow, Rotating liquids. (MJM).
Download or read book Numerical Simulation of Unsteady Incompressible Flow Past Two dimensional Elliptic Cylinders written by Ayan Sengupta and published by . This book was released on 2003 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unsteady algorithms Fully Implicit and Crank Nicholson were developed for body fitted curvilinear coordinate system to study the incompressible flow over two-dimensional ellipses. In addition, explicit cyclic boundary condition was implemented to facilitate analysis of vortex shedding. Unsteady flow over circular cylinders was simulated for different Reynolds numbers and compared with experimental data. Flow over ellipses was simulated to study the effect of aspect ratio on drag coefficient. It was observed that the drag coefficient increased as the aspect ratio increased reaching an asymptotic value as the ellipse approached a flat plate.

This book was released on 2009-09-29 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Volume is the Proceedings of the IUTAM Symposium on Unsteady Separated Flows and Their Control held in Corfu, Greece, 18–22 June 2007. This was the second IUTAM Symposium on this subject, following the symposium in Toulouse, in April 2002. The Symposium consisted of single plenary sessions with invited lectures, - lected oral presentations, discussions on special topics and posters. The complete set of papers was provided to all participants at the meeting. The thematic sessions of this Symposium are presented in the following: Experimental techniques for the unsteady ow separation Theoretical aspects and analytical approaches of ow separation Instability and transition Compressibility effects related to unsteady separation Statistical and hybrid turbulence modelling for unsteady separated ows Direct and Large-Eddy Simulation of unsteady separated ows Theoretical/industrial aspects of unsteady separated ow control This IUTAM Symposium concerned an important domain of Theoretical and Applied Mechanics nowadays. It focused on the problem of ow separation and of its control. It achieved a uni ed approach regrouping the knowledge provided from theoretical, experimental, numerical simulation and modelling aspects for unsteady separated ows (incompressible and compressible regimes) and included ef cient control devices to achieve attenuation or suppression of separation. The subject - eas covered important themes in the domain of fundamental research as well as in the domain of applications.

Download or read book Hydrodynamics Around Cylindrical Structures written by Jorgen Fredsoe and published by World Scientific. This book was released on 1997-03-17 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the subject of wave/current flow around a cylinder, the forces induced on the cylinder by the flow, and the vibration pattern of slender structures in a marine environment.The primary aim of the book is to describe the flow pattern and the resulting load which develops when waves or current meet a cylinder. Attention is paid to the special case of a circular cylinder. The development in the forces is related to the various flow patterns and is discussed in detail. Regular as well as irregular waves are considered, and special cases like wall proximities (pipelines) are also investigated.The book is intended for MSc students with some experience in basic fluid mechanics and for PhD students.

Download or read book Study of Flow Past Elliptic and Circular Cylinders Using Direct Numerical Simulation written by Rajat Mittal and published by . This book was released on 1995 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow over elliptic cylinders can be considered prototypical of flow over a range of bluff bodies since the geometry allows one to study the effect of both thickness and angle-of-attack on the flow field. Therefore a careful study of this flow should provide valuable insight into the phenomenon of unsteady separation and the structure of bluff body wakes. With this in mind, a spectral collocation technique has been developed to simulate the three-dimensional incompressible flow over elliptic cylinders and unlike spectral element and spectral multi-domain techniques, here the flow is solved in a single domain. The equations are discretized on a body fitted elliptic cylindrical grid and properties of the metric associated with this coordinate system are used to solve the governing equations in an efficient manner. Other key issues including the inflow and outflow boundary conditions and time-discretization are discussed in detail with the hope that this will facilitate future simulations of simdar flows.
Download or read book Numerical Study of a Viscous Fluid Past a Circular Cylinder written by Mitutosi Kawaguti and published by . This book was released on 1965 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic numerical study of the unsteady viscous incompressible fluid flow past a circular cylinder is reported. The range of the Reynolds number considered is 1 to 100. The steady state solutions could be obtained at the Reynolds numbers R = 10, 20, 30, 40, 50 as the limit of the unsteady state solutions. The numerical results are compared with those for the steady problem and they are found to be in agreement. Dependency on the Reynolds number and the time of the flow pattern, vorticity distribution, pressure distribution and the drag are shown. (Author).
Download or read book Bluff Body Wakes Dynamics and Instabilities written by Helmut Eckelmann and published by Springer. This book was released on 2014-10-05 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bluff-body wakes play an important role in many fluid dynamics problems and engineering applications. This book gives and up-to-date account of recent results obtained in the study of bluff-body wakes. Experimental, theoretical and numerical approaches are all comprehensively covered and compared. Topics of particular interest include hydrodynamic instability analyses, three-dimensional pattern formation problems, flow control methods, bifurcation analyses, numerical simulations and turbulence modelling. The main originality of thisvolume is that recent conceptual advances made to describe nonlinear phenomena in general are put to the test on a classical problem in fundamental fluid mechanics, namely the wake structure generated behind a bluff object.
