Experiments on transitional regime sediment density flows and resulting deposits
… regarding the sedimentary deposits of submarine density flows. Certain density flows may transition from a more turbulent to a more coherent flow regime e.g. by a loss of velocity in flows with large concentrations of suspended sediment. Such transitional flows are produced when turbulence …

Sedimentology and Stratigraphy of Glacial Lake Souris, North Dakota: effects of a glacial-lake outburst
… Regina outburst on the lake that received the flows, Glacial Lake Souris.</p> <p>Glacial Lake Souris, located in what is now North Dakota, was inundated by about 74 km3 of water carrying 25 km3 of sediment from the outburst of Lake Regina (Saskatchewan). Prior to the outburst, the bottom of …

Nonlinear and non-modal stability of structures evolving in shear flows
… structures that develop in various constant density flows. In particular, the stability of nonlinear structures which develop in rotating plane Couette flow is analyzed using Floquet theory, which allows the global stability of an important secondary nonlinear structure called a Taylor vortex …

Rayleigh-Taylor mixing: confinement by stratification and geometry
… stratification, and by impingement on a stable density interface. Water-based experiments are modelled using a variety of techniques, ranging from simple hand calculation of energy exchange to full three-dimensional numerical simulation. Since there are well known difficulties in modelling …

Phase-space representation of digital holographic and light field imaging with application to two-phase flows
… underwater research, in particular, two-phase flows measurements, are presented. The techniques under study, digital holographic imaging and light field imaging, are targeted at different flow conditions. In low-density flows, particles and air bubbles in water can be imaged by a digital …

The Effects of Basin Slope and Boundary Friction on the Character and Plunge Location of Hyperpycnal Flows Entering a Laterally Unbounded Basin
… in river mouth discharges. The plunging of high density flows in two dimensional channels has been extensively studied before. A fundamental assumption in these studies is that the flow is laterally confined. These studies allow the flow to plunge only in two directions, the horizontal …

Solution of strained edge flames by a boundary value method
… eigenvalue problem based on the variable-density zero Mach number reactive Navier-Stokes equations. It employs a homotopy method to gradually map the solutions from the constant-density edge flame to the more challenging variable-density edge flame. The flow and the combustion fields are …

DEPOSITIONAL SYSTEMS INTERPRETATION OF EARLY PERMIAN MIXED SILICICLASTICS AND CARBONATES, MIDLAND BASIN, TEXAS
… suspension settling, bottom currents, or dilute density flows. In contrast, carbonate rich facies are interpreted as deposited by a spectrum of sediment gravity flow processes. Moderate to high levels of bioturbation in all clay and silt rich facies suggests dysoxic to suboxic conditions within …

Modelling of turbulent swirling flows
… and reacting anistropic turbulent, swirling flows using popular turbulence models with a robust numrical procedure. The performance of these turbulence models is assessed and compared against experimental data for anisotropic, turbulent swirling flow in a cylindrical pipe and non-reacting and …

A Higher-Order VOF Interface Reconstruction Scheme for Non-Orthogonal Structured Grids - with Application to Surface Tension Modelling
… the purpose of simulating liquid-gas interfacial flows numerically. The key strength of VOF is its mass conserving property. However, interface reconstruction is required when geometric properties such as curvature need to be accurately computed. For surface tension modelling in particular, …

Advances in Gromov–Wasserstein optimal transport: linearization, multi-marginal generalization, barycenters and transfer operators
… between initial and final state in the form of density flows. Firstly, we discuss a completely unsupervised approach in the extreme setting when no correspondence information between initial and final state are known, but the system is expected to admit a governing isometric force such as …
