Book Description
This text presents the techniques for a wide set of applications, ranging from the problems of size and shape optimization (historically the first to be studied) to topology and material optimization. Structural models are considered that use both discrete and finite elements. Structural materials can be classical or new. Emerging methods are also addressed, such as automatic differentiation, intelligent structures optimization, integration of structural optimization in concurrent engineering environments, and multidisciplinary optimization.

Machine Learning Control – Taming Nonlinear Dynamics and Turbulence
Author: Thomas Duriez
Publisher: Springer
ISBN: 3319406248
Category : Technology & Engineering
Languages : en
Pages : 229
Book Description
This is the first textbook on a generally applicable control strategy for turbulence and other complex nonlinear systems. The approach of the book employs powerful methods of machine learning for optimal nonlinear control laws. This machine learning control (MLC) is motivated and detailed in Chapters 1 and 2. In Chapter 3, methods of linear control theory are reviewed. In Chapter 4, MLC is shown to reproduce known optimal control laws for linear dynamics (LQR, LQG). In Chapter 5, MLC detects and exploits a strongly nonlinear actuation mechanism of a low-dimensional dynamical system when linear control methods are shown to fail. Experimental control demonstrations from a laminar shear-layer to turbulent boundary-layers are reviewed in Chapter 6, followed by general good practices for experiments in Chapter 7. The book concludes with an outlook on the vast future applications of MLC in Chapter 8. Matlab codes are provided for easy reproducibility of the presented results. The book includes interviews with leading researchers in turbulence control (S. Bagheri, B. Batten, M. Glauser, D. Williams) and machine learning (M. Schoenauer) for a broader perspective. All chapters have exercises and supplemental videos will be available through YouTube.

Convection in Rotating Fluids
Author: B.M. Boubnov
Publisher: Springer Science & Business Media
ISBN: 9401102430
Category : Science
Languages : en
Pages : 236
Book Description
Spatial inhomogeneity of heating of fluids in the gravity field is the cause of all motions in nature: in the atmosphere and the oceans on Earth, in astrophysical and planetary objects. All natural objects rotate and convective motions in rotating fluids are of interest in many geophysical and astrophysical phenomena. In many industrial applications, too (crystal growth, semiconductor manufacturing), heating and rotation are the main mechanisms defining the structure and quality of the material. Depending on the geometry of the systems and the mutual orientation of temperature and gravity field, a variety of phenomena will arise in rotating fluids, such as regular and oscillating waves, intensive solitary vortices and regular vortex grids, interacting vortices and turbulent mixing. In this book the authors elucidate the physical essence of these phenomena, determining and classifying flow regimes in the space of similarity numbers. The theoretical and computational results are presented only when the results help to explain basic qualitative motion characteristics. The book will be of interest to researchers and graduate students in fluid mechanics, meteorology, oceanography and astrophysics, crystallography, heat and mass transfer.

Numerical Simulation of Viscous Shock Layer Flows
Author: Y.P. Golovachov
Publisher: Springer Science & Business Media
ISBN: 9401584907
Category : Mathematics
Languages : en
Pages : 359
Book Description
The book is concerned with mathematical modelling of supersonic and hyper sonic flows about bodies. Permanent interest in this topic is stimulated, first of all, by aviation and aerospace engineering. The designing of aircraft and space vehicles requires a more precise prediction of the aerodynamic and heat transfer characteristics. Together with broadening of the flight condition range, this makes it necessary to take into account a number of gas dynamic and physical effects caused by rarefaction, viscous-inviscid interaction, separation, various physical and chemical processes induced by gas heating in the intensive bow shock wave. The flow field around a body moving at supersonic speed can be divided into three parts, namely, shock layer, near wake including base flow, and far wake. The shock layer flow is bounded by the bow shock wave and the front and lat eral parts of the body surface. A conventional approach to calculation of shock layer flows consists in a successive solution of the inviscid gas and boundary layer equations. When the afore-mentioned effects become important, implementation of these models meets difficulties or even becomes impossible. In this case, one has to use a more general approach based on the viscous shock layer concept.

Shaped Crystal Growth
Author: V.A. Tatarchenko
Publisher: Springer Science & Business Media
ISBN: 9401729883
Category : Technology & Engineering
Languages : en
Pages : 292
Book Description
The monograph "Shaped Crystal Growth" by V. A. Tatarchenko is the first systematic of the macroscopic crystallization theory. The theory is based on the stable statement growth conception, which means that self-stabilization is present in the system, with growth parameter deviations occurring under the action of external perturbations attenuating with time. The crystallization rate is one of the parameters responsible for crystal defect formation. Steady-state crystal growth means that crystallization rate internal stabilization is present, thus allowing more perfect crystals to grow. Most important is the fact that the crystal shape (an easily observed parameter) is one of the stable-growth characteristics when growing crystals without any contact with the crucible walls. This means that constant-cross-section crystal growth is to a certain extent evidence of crystallization process stability. The principles of the stable crystal growth theory were developed by the author of the monograph in the early 1970s. Due to the efforts over the past 20 years of V. A. Tatarchenko, his disciples (V. A. Borodin, S. K. Brantov, E. A. Brener, G. I. Romanova, G. A. Satunkin et al) and his followers (B. L. Timan, 0. V. Kolotiy et al) the theory has been completed, which is demonstrated by this monograph. The characteristic feature of the theory is its trend towards solving practical problems that occur in the process of crystal growth.
