A High-order Compact Finite-difference Scheme for Large-eddy Simulation of Active Flow Control
Author: Donald Pasquale RizzettaPublisher:
ISBN:
Category : Eddies
Languages : en
Pages : 106
Book Description
A computational approach for performing large-eddy simulation (LES) of flows with active control is summarized. Simulation of these problems typically characterized by small-scale fluid structures cannot be carried out accurately by methods less sophisticated than LES. The numerical scheme is predicated upon an implicit time-marching algorithm, and utilizes a high order compact finite-difference approximation to represent spatial derivatives. Robustness of the scheme is maintained by employing a low-pass Pade-type non-dispersive spatial filter, which also serves as an implicit sub-grid turbulent model. Geometrically complex applications are accommodated by a high order overset grid technique. Utility of the method is illustrated by steady and pulsed approaches to suppression of acoustic resonance in supersonic cavity flow, leading-edge vortex control of a delta wing, efficiency enhancement of a transitional highly loaded low-pressure turbine blade, and separation control of a wall-mounted hump model. Where available, comparisons are also made with experimental data.

Internal Flow
Author: E. M. GreitzerPublisher: Cambridge University Press
ISBN: 1139451111
Category : Technology & Engineering
Languages : en
Pages : 739
Book Description
This book describes the analysis and behaviour of internal flows encountered in propulsion systems, fluid machinery (compressors, turbines and pumps) and ducts (diffusers, nozzles and combustion chambers). The focus is on phenomena that are important in setting the performance of a broad range of fluid devices. The authors show that even for complex processes one can learn a great deal about the behaviour of such devices from a clear understanding and rigorous use of basic principles. Throughout the book they illustrate theoretical principles by reference to technological applications. The strong emphasis on fundamentals, however, means that the ideas presented can be applied beyond internal flow to other types of fluid motion. The book equips students and practising engineers with a range of new analytical tools. These tools offer enhanced interpretation and application of both experimental measurements and the computational procedures that characterize modern fluids engineering.
