Book excerpt: Under resolved computer simulations are typically unavoidable in many practical turbulent flow applications exhibiting extreme geometrical complexity and broad ranges of length and time scales. In such applications, coarse grained simulation becomes the effective simulation strategy, mostly by necessity rather than by choice. In coarse grained simulation strategies, resolved/unresolved scale separation is assumed possible, large energy containing structures are mostly resolved, smaller structures are spatially filtered out, and unresolved subgrid effects are modeled. The subject of this work is on implicit large-eddy simulation which relies on subgrid modeling implicitly provided by physics capturing numerical algorithms. Predictability issues of coarse grained simulation from the perspective of implicit large-eddy simulation of under resolved mixing of material scalars driven by under resolved velocity fields and initial conditions are addressed. The performance of implicit large-eddy simulation in the contexts of forced scalar mixing, transition to turbulence and turbulence decay, and shock-driven turbulent mixing is the particular focus.

Book Synopsis Implicit Large Eddy Simulation by : Fernando F. Grinstein

Download or read book Implicit Large Eddy Simulation written by Fernando F. Grinstein. This book was released on 2011-02-17. Available in PDF, EPUB and Kindle. Book excerpt: The numerical simulation of turbulent flows is a subject of great practical importance to scientists and engineers. The difficulty in achieving predictive simulations is perhaps best illustrated by the wide range of approaches that have been developed and are still being used by the turbulence modeling community. In this book the authors describe one of these approaches, Implicit Large Eddy Simulation (ILES). ILES is a relatively new approach that combines generality and computational efficiency with documented success in many areas of complex fluid flow. This book synthesizes the theoretical basis of the ILES methodology and reviews its accomplishments. ILES pioneers and lead researchers combine here their experience to present a comprehensive description of the methodology. This book should be of fundamental interest to graduate students, basic research scientists, as well as professionals involved in the design and analysis of complex turbulent flows.

Book Synopsis Coarse Grained Simulation and Turbulent Mixing by : Fernando F. Grinstein

Download or read book Coarse Grained Simulation and Turbulent Mixing written by Fernando F. Grinstein. This book was released on 2016-06-30. Available in PDF, EPUB and Kindle. Book excerpt: Small-scale turbulent flow dynamics is traditionally viewed as universal and as enslaved to that of larger scales. In coarse grained simulation (CGS), large energy-containing structures are resolved, smaller structures are spatially filtered out, and unresolved subgrid scale (SGS) effects are modeled. Coarse Grained Simulation and Turbulent Mixing reviews our understanding of CGS. Beginning with an introduction to the fundamental theory the discussion then moves to the crucial challenges of predictability. Next, it addresses verification and validation, the primary means of assessing accuracy and reliability of numerical simulation. The final part reports on the progress made in addressing difficult non-equilibrium applications of timely current interest involving variable density turbulent mixing. The book will be of fundamental interest to graduate students, research scientists, and professionals involved in the design and analysis of complex turbulent flows.
