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.

Book Synopsis On the Simulation of Shock-driven Material Mixing in High-Re Flows (u). by :
Download or read book On the Simulation of Shock-driven Material Mixing in High-Re Flows (u). written by . This book was released on 2009. Available in PDF, EPUB and Kindle. Book excerpt: Implicit large eddy simulation proposes to effectively rely on the use of subgrid modeling and filtering provided implicitly by physics capturing numerics. Extensive work has demonstrated that predictive simulations of turbulent velocity fields are possible using a class of high resolution, non-oscillatory finite-volume (NFV) numerical algorithms. Truncation terms associated with NFV methods implicitly provide subgrid models capable of emulating the physical dynamics of the unresolved turbulent velocity fluctuations by themselves. The extension of the approach to the substantially more difficult problem of under-resolved material mixing by an under-resolved velocity field has not yet been investigated numerically, nor are there any theories as to when the methodology may be expected to be successful. Progress in addressing these issues in studies of shock-driven scalar mixing driven by Ritchmyer-Meshkov instabilities will be reported in the context of ongoing simulations of shock-tube laboratory experiments.

Book Synopsis On the Predictability of Turbulent Mixing with Implicit Large-eddy Simulation by : Adam Joseph Wachtor
Download or read book On the Predictability of Turbulent Mixing with Implicit Large-eddy Simulation written by Adam Joseph Wachtor. This book was released on 2012. Available in PDF, EPUB and Kindle. 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.
