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.

Shock Wave-Boundary-Layer Interactions
Author: Holger BabinskyPublisher: Cambridge University Press
ISBN: 1139498649
Category : Technology & Engineering
Languages : en
Pages : 481
Book Description
Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.
