Available in PDF, EPUB and Kindle. Book excerpt: In this project we have sought to understand and locate coherent material structures that govern turbulent fluid mixing. As we have showed, these structures coincide with invariant manifolds of the fluid particle dynamics. We have developed several numerically assisted analytic criteria to extract invariant manifolds from simulated and measured flow data. Our criteria have been applied by others in analyzing controlled shear flows I, vortex merger problems 2, geophysical data 3, and geological phenomena 4. As an example, Fig. 1 shows coherent structures rendered by our criteria in a two-dimensional turbulence simulation. Unexpectedly, we have also managed to extend Prandtl's classic steady flow separation criterion to unsteady flows. Remarkably, we also obtained explicit asymptotic formulae for unsteady separation profiles near a general no-slip boundary. As an example, Figure 2. compares a separation prediction from the widely used "zero-skin friction principle" (Fig. 2a), and from our unsteady separation criterion (Fig. 2b). Figure 3. (a) Instantaneous streamlines, separation points predicted the classical theory (zero skin friction), and actual unsteady flow separation. Separation is visualized by plotting the current position of an initially horizontal layer of fluid particles in the oscillating separation bubble model of S. Ghosh (UTRC). (b)Same as (a), with our analytically predicted unsteady separation profile superimposed. In a new approach to flow control, we have explored the use invariant manifolds to shape global coherent structures via local feedback control. We have applied these ideas in the control of advective mixing behind the flameholder of a combustor and the control of unsteady separation in bluff body shear flows (see Fig. 3).
Book Synopsis Model-based Nonlinear Control of Aeroengines by : Jiqiang Wang
Download or read book Model-based Nonlinear Control of Aeroengines written by Jiqiang Wang and published by Springer Nature. This book was released on 2021-08-17 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to develop systematic design methodologies to model-based nonlinear control of aeroengines, focusing on (1) modelling of aeroengine systems—both component-level and identification-based models will be extensively studied and compared; and (2) advanced nonlinear control designs—set-point control, transient control and limit-protection control approaches will all be investigated. The model-based design has been one of the pivotal technologies to advanced control and health management of propulsion systems. It can fulfil advanced designs such as fault-tolerant control, engine modes control and direct thrust control. As a consequence, model-based design has become an important research area in the field of aeroengines due to its theoretical interests and engineering significance. One of the central issues in model-based controls is the tackling of nonlinearities. There are publications concerning with either nonlinear modelling or nonlinear controls; yet, they are scattered throughout the literature. It is time to provide a comprehensive summary of model-based nonlinear controls. Consequently, a series of important results are obtained and a systematic design methodology is developed which provides consistently enhanced performance over a large flight/operational envelope, and it is thus expected to provide useful guidance to practical engineering in aeroengine industry and research.

Book Synopsis Robust Multivariable Control of Aerospace Systems by : Declan Bates
Download or read book Robust Multivariable Control of Aerospace Systems written by Declan Bates and published by IOS Press. This book was released on 2002 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical design and analysis techniques, many of which date back to the 1950's, are still predominantly used in the aerospace industry for the design and analysis of automatic flight control and aero-engine control systems. The continued success and popularity of these techniques is particularly impressive considering the radical advances in aircraft and spacecraft design and avionics technology made over this period. Clearly, an understanding of both the advantages and limitations of these methods is essential in order to properly evaluate the likely usefulness of more modern techniques for the design and analysis of aerospace control systems. One of the themes of this book is that the multivariable robust control methods it describes are logical and natural extensions of the more classical methods, and not replacements for them. It is assumed that readers of this publication are already familiar with classical flight control techniques. Emphasis is on the philosophy, advantages and limitations of the classical approach to flight control system design and analysis. Abstracted in Inspec
