Abstract

Sand, rice, sugar, snow, cement... Although ubiquitous in our daily lives, granular media still challenge engineers and fascinate researchers. This book provides the state-of-the-art of the physics of granular media and recent advances in the field. The book presents the fundamental properties of granular materials: interactions between grains; solid, liquid and gaseous behaviours; coupling with a fluid; and sediment transport and formation of geological structures. Descriptions of the phenomena combine qualitative and formal arguments, coming from areas as diverse as elasticity, plasticity, statistical physics, fluid mechanics and geomorphology. Many examples of the astonishing behaviours of granular media are presented, including avalanches, segregation, dune song and quicksand. This book is ideal for graduate students and researchers in physics, applied mathematics and engineering.

Abstract

Der Bericht behandelt die Entwicklung strömungsmechanischer Modelle sowie deren Anwendung in der Praxis. Es werden das Schallkriterium der schiefen Stoßreflexion, die Stabilitätstheorie lokaler Störungen zur effizienten Strömungskontrolle, Transitionsmodelle dreidimensionaler Grenzschichten und Nachlauströmungen sowie thermischer Instabilitäten und in der Bioströmungsmechanik Strömung-Struktur gekoppelte Modelle des Vogelfluges und des menschlichen Herzens entwickelt und validiert. The report deals with the development of fluid mechanical models as well as with their practical applications. The sonic criterion of oblique shock reflexion, stability theory of local disturbances for efficient flow control, transition models of three-dimensional boundary layers and wakes as well as thermal instabilities and in biofliud mechanics fluid-structure coupled models of the bird flight and human heart have been developed and validated.

Abstract

Turbulence is ubiquitous in science, technology and daily life and yet, despite years of research, our understanding of its fundamental nature is still tentative and incomplete. More generally, the tools required for a deep understanding of strongly interacting many-body systems remain underdeveloped. Inspired by a research programme held at the Newton Institute in Cambridge, this book contains reviews by leading experts that summarize our current understanding of the nature of turbulence from theoretical, experimental, observational and computational points of view. The articles cover a wide range of topics, including the scaling and organized motion in wall turbulence, small scale structure, dynamics and statistics of homogeneous turbulence, turbulent transport and mixing, and effects of rotation, stratification and magnetohydrodynamics, as well as superfluidity. The book will be useful to researchers and graduate students interested in the fundamental nature of turbulence at high Reynolds numbers.

Abstract

Neue Methoden für Lumped-Parameter-Nodalisierungen werden auf ein Reaktorsicherheitsbehälter-Modell des Integralcodes MELCOR angewendet. Wasserstoffverteilungen aus MELCOR und GASFLOW (3D-CFD) werden verglichen. Die verbesserte Nodalisierung führt zu deutlich erhöhter Genauigkeit. New methods for enhancing the Lumped Parameter nodalization of a nuclear reactor containment are applied to a model of the integral code MELCOR. Hydrogen distributions calculated by MELCOR and the 3D-CFD code GASFLOW are compared. The enhanced nodalization increases the accuracy significantly.

Abstract

This book presents a non-traditional approach to the theory of turbulence. Its objective is to prove that Newtonian mechanics is fully equipped for the description of turbulent motions without the help of experimentally obtained closures. Turbulence is one of the most fundamental problems in theoretical physics that is still unsolved. The term ""unsolved"" here means that turbulence cannot be properly formulated, i.e. reduced to standard mathematical procedure such as solving differential equations. In other words, it is not just a computational problem: prior to computations, a consistent mat
