Book excerpt: Back Cover Text: This book addresses the study of the gaseous state of granular matter in the conditions of rapid flow caused by a violent and sustained excitation. In this regime, grains only touch each other during collisions and hence, kinetic theory is a very useful tool to study granular flows. The main difference with respect to ordinary or molecular fluids is that grains are macroscopic and so, their collisions are inelastic. Given the interest in the effects of collisional dissipation on granular media under rapid flow conditions, the emphasis of this book is on an idealized model (smooth inelastic hard spheres) that isolates this effect from other important properties of granular systems. In this simple model, the inelasticity of collisions is only accounted for by a (positive) constant coefficient of normal restitution. The author of this monograph uses a kinetic theory description (which can be considered as a mesoscopic description between statistical mechanics and hydrodynamics) to study granular flows from a microscopic point of view. In particular, the inelastic version of the Boltzmann and Enskog kinetic equations is the starting point of the analysis. Conventional methods such as Chapman-Enskog expansion, Grad’s moment method and/or kinetic models are generalized to dissipative systems to get the forms of the transport coefficients and hydrodynamics. The knowledge of granular hydrodynamics opens up the possibility of understanding interesting problems such as the spontaneous formation of density clusters and velocity vortices in freely cooling flows and/or the lack of energy equipartition in granular mixtures. Some of the topics covered in this monograph include: Navier-Stokes transport coefficients for granular gases at moderate densities Long-wavelength instability in freely cooling flows Non-Newtonian transport properties in granular shear flows Energy nonequipartition in freely cooling granular mixtures Diffusion in strongly sheared granular mixtures Exact solutions to the Boltzmann equation for inelastic Maxwell models

Download or read book Global Stability Analysis of Shear Flows written by Rameshkumar Bhoraniya and published by Springer Nature. This book was released on 2023-03-10 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the fundamentals and advanced research on the global stability analysis of the shear flows. The contents investigate the results of global stability analysis for different configurations of internal and external shear flows. The topics covered are global stability analysis of converging-diverging channel flows, axisymmetric boundary layer developed on a circular cylinder, cone and inclined flat-plate boundary layer, and wall jets. It further explains the effect of divergence, convergence, transverse curvature, and pressure gradients on the global stability of the different configurations of shear flows. The book is a valuable reference for beginners, researchers, and professionals working in the field of aerodynamics and marine hydrodynamics.

Download or read book From Instabilities to Turbulence in Rotating Stratied Ows with Horizontal and Vertical Shear written by Eric Moore Arobone and published by . This book was released on 2014 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two idealized rotating and stratified flows are explored using linear stability analysis and three-dimensional direct numerical simulations. The first problem explores barotropic mean flow containing horizontally-oriented shear flow in the form of a mixing layer. The second problem explores a uniform baroclinic mean flow in the form of a homogeneous density front in thermal wind balance with uniform vertical shear. Both flows are explored using Richardson and Rossby numbers appropriate for submesoscale shear flows, with lateral length scales of roughly 1 to 20 kilometers. The horizontal shear flow results in simultaneous inertial and barotropic instabilities provided the mixing layer vorticity is opposite in sign and substantially greater in magnitude than the Coriolis parameter. When the vorticity of the mixing layer is opposite in sign and similar in magnitude to the Coriolis parameter the barotropic instability is fundamentally altered. The vertical wavenumber associated with this new instability increases by an order of magnitude destabilizing barotropic vortices leading to increased turbulence intensity well outside of the inertially unstable regime. Symmetric instability (fluctuations have no along-front variation and are aligned with isopycnals) has been identified in the literature as a potential route to turbulence at fronts as an alternative to wind-driven boundary layer mixing. Linear analysis and simulations of a uniform baroclinic flow in initial geostrophic balance performed here suggest that the instability responsible for initiating transition to turbulence should be near-symmetric and not exactly symmetric as predicted for asymptotically large time scales. Owing to near-symmetry, the instability fundamentally differs from the purely symmetric instability due to currents crossing surfaces of constant density and tapping the reservoir of potential energy available in the front. The presence of strong vertical shear only intensifies this effect as time increases. A highly-resolved turbulent simulation demonstrates a pathway to turbulence from quiescent flow via near-symmetric currents which succumb to shear-convective instabilities which in turn act to destabilize vorticity fluctuations aligned with the mean vorticity in the base flow. Once these fluctuations are sufficiently strong enough, the flow three--dimensionalizes and rapidly breaks down into turbulence throughout the domain.
