Sampling From Stratified Spaces
… Limit Theorems (CLTs) of Frechet means on stratified spaces. The broad goal of this work is to answer the following question: What information one should expect to get by sampling from a stratified space? In particular, this work explores relationships between geometry and different forms …

Heat transfer in stratified flow.
When water is drawn from a cooling pond, heated by some industrial process and discharged "back into the pond to dissipate its heat load to the atmosphere an orderly motion is generated within the pond. This motion and the subsequent heat transfer from the surface of the pond is governed by the …

Modelling of turbulent stratified flames
… operating a globally lean system is to employ a stratified premixed mode where areas of richer mixture are used to enhance the stability of the flame. In this thesis a computational modelling methodology for the simulation of stratified premixed flames is developed. Firstly, several sub-models …

Experiments on Stratified Multiphase Plumes
… dynamics, especially when rising through density stratified environments such as the ocean or the atmosphere. In this thesis, four experimental studies are presented investigating the dynamic behaviour of both particle-laden plumes and bubble plumes in stratified ambients. Experiments on …

Functional quantization-based stratified sampling
Functional quantization-based stratified sampling is a method for variance reduction proposed by Corlay and Pagès (2015). This method requires the ability to both create functional quantizers and to sample Brownian paths from the strata defined by the quantizers. We show that product quantizers are …

Sedimentation in a stratified ambient
… the interaction between settling particles and a stratified ambient in a variety of contexts. We first study the generation of large scale fluid motions by the localised release of a finite mass of particles in the form of plumes or gravity currents. We present the results of a combined …

Shear flow instabilities in stratified magnetohydrodynamics
… important motivating example is the thin stably-stratified region in the Sun known as the tachocline, wherein the turbulent dynamics are believed to be driven by shear flow instabilities. In this thesis we investigate how stable stratification and magnetic fields affect instabilities of a …

Homogeneous and stratified vented gas explosions
… into the influence of homogeneous and stratified mixtures was undertaken by varying mixture reactivity, ignition position, injection position and mixture composition. A feature of this work has been the similarities in explosion phenomena between stratified and homogeneous explosions …

Dynamics of Periodic Stratified Shear Flows
In questa tesi studiamo le instabilità in fluidi stratificati laminari dove la stratificazione in densità ha un effetto stabilizzante. Nonostante l idea comune che la forza d Archimede abbia un effetto stabilizzante, in alcune circostanze tale stratificazione ha mostrato di poter indurre …

Continuously Stratified Flow Dynamics Over a Hollow
… the effects of a hollow on a continuously stratified flow. Measurements showed an acceleration of the near-bottom flow as it moved toward the deepest part of the hollows, in contrast to the deceleration expected from two-dimensional Bernoulli-type dynamics. The acceleration was attributed …

Symplectic toric stratified spaces with isolated singularities
… symplectic toric cones and symplectic toric stratified spaces with isolated singularities. Both types of object are classified via orbital moment map and a second degree cohomology class. As symplectic toric stratified spaces with isolated singularities are locally modeled on symplectic toric …

Energetics and mixing in stratified turbulent flows
… the upwelling of water through the stably stratified ocean interior, needed to close the global circulation, is only possible through the enhanced vertical mixing resulting from turbulence. The transport of heat, carbon and nutrients is also affected by this mixing. Understanding its …

Laminar flame propagation in a stratified charge
… or stoichiometric mixture to a lean mixture in a stratified methane-air charge was investigated experimentally and numerically. Emphasis was on the understanding of the flame behavior in the transition region; in particular, on the mechanism of burning velocity enhancement in this region. In the …

On the Homotopy Theory of Stratified Spaces
… dedicated to proving a 'homtopy hypothesis' for stratified spaces. Specifically, given a poset P, we show that the ∞-category Strₚ of ∞-categories with a conservative functor to P can be obtained from the ordinary category of P-stratified topological spaces by inverting a class of weak …
