Abstract:

This thesis presents a method for simulating fluids on a view dependent grid structure to exploit level-of-detail with distance to the viewer. Current computer graphics techniques, such as the Stable Fluid and Particle Level Set methods, are modified to support a nonuniform simulation grid. In addition, infinite fluid boundary conditions are introduced that allow fluid to flow freely into or out of the simulation domain to achieve the effect of large, boundary free bodies of fluid. Finally, a physically based rendering method known as photon mapping is used in conjunction with ray tracing to g

Abstract:

This thesis aims at presenting the studies conducted using computational modeling for understanding physiology of glottis and mechanism of phonation. The process of phonation occurs in the larynx, commonly called the voice box, due to the self-sustained vibrations induced in the vocal folds by the airflow. The physiology of glottis can be understood using fluid dynamics which is a vital process in developing and discovering voice disorder treatments. Simulations have been performed on a simplified two-dimensional version of the glottis to study the behavior of the vocal folds with help of flui

The concept of moving surface boundary-layer control, as applied to the Joukowsky and NACA airfoils, is investigated through a planned experimental program complemented by theoretical and flow visualization studies. The moving surface was provided by one or two rotating cylinders located at the leading edge, the trailing edge, or the top surface of the airfoil. Three carefully designed two-dimensional models, which provided a wide range of single and twin cylinder configurations, were tested at a subcritical Reynolds number (Re = 4.62 x 10⁴ or Re — 2.31 x 10⁵) in a laminar-flow tunnel over a r

Abstract:

This thesis considers various extensions to the fluid/gravity correspondence as well as problems fundamental to the study of fluid dynamics. The fluid/gravity correspondence is a map between the solutions of the Navier-Stokes equations of fluid dynamics and the solutions of the Einstein equations in one higher spatial dimension. This map arose within the context of string theory and holography and is a specific realisation of a much wider class of dualities known as the Anti de Sitter/Conformal Field Theory (AdS/CFT) correspondence.

Abstract:

The detonation of an explosive in water leads to a complex set of chemical and physical phenomena. When the detonation wave reaches the surface of the explosive it reacts violently with the water, producing a shock wave propagating outwards and also a nearly spherical gaseous bubble of detonation products. The fact that the characteristic time scales of these two phenomena differ by approximately two orders of magnitude has often been exploited by utilising independent models to describe the shock and the bubble. In this thesis both the shock and the bubble are examined using a range of method

Abstract:

Bubbly flows can be found in many applications in chemical, biological and power engineering. Reliable simulation tools of such flows that allow the design of new processes and optimization of existing one are therefore highly desirable. CFD-simulations applying the multi-ﬂuid approach are very promising to provide such a design tool for complete facilities. In the multi-fluid approach, however, closure models have to be formulated to model the interaction between the continuous and dispersed phase. Due to the complex nature of bubbly flows, different phenomena have to be taken into account an

In this thesis, the exploitation of computational fluid dynamics (CFD) methods for the flight dynamics of manoeuvring aircraft is investigated. It is demonstrated that CFD can now be used in a reasonably routine fashion to generate stability and control databases. Different strategies to create CFD-derived simulation models across the flight envelope are explored, ranging from combined low-fidelity/high-fidelity methods to reduced-order modelling. For the representation of the unsteady aerodynamic loads, a model based on aerodynamic derivatives is considered. Static contributions are obtained

Abstract:

The coupling of computational fluid dynamics and rigid body dynamics promises enhanced multidisciplinary simulation capability for aircraft design and certification. Industrial application of such coupled simulations is limited however by computational cost. In this context, model reduction can retain the fidelity of the underlying model while decreasing the overall computational effort. Thus, investigation of such coupled model reduction is presented in this thesis. The technique described herein relies on an expansion of the full order non-linear residual function in a truncated Taylor serie

This thesis focuses on the numerical simulation of yacht sails using both computational fluid dynamics (CFD) and fluid structure interaction (FSI) modelling. The modelling of yacht sails using RANS based CFD and the SST turbulence model is justified with validation against wind tunnel studies (Collie, 2005; Wilkinson, 1983). The CFD method is found to perform well, with the ability to predict flow separation, velocity and pressure profiles satisfactorily. This work is extended to look into multiple sail interaction and the impact of the mast upon performance. A FSI solution is proposed next, c

Structures conveying mass lose stability once the mass exceeds a certain critical velocity. The type of instability observed depends on the nature of the supports that the structure has. If the structure (beam or pipe) is cantilevered (thereby deeming it a nonconservative system), Âgarden-hose-likeÂ flutter instability is observed once a critical velocity is exceeded. When studying the flutter instability of a cantilevered pipe (including shear deformation) by strictly a linear theory, it has been demonstrated through numerical integration that the values of the critical velocity are only va

The local dynamics of sandwaves and their crest-shedding turbulent flows has received little mechanistic attention, unlike recent advances in allied fields such as bubbly shear flows.

Experimental studies were conducted on the trajectories of model particles over suitably scaled fixed bedforms in a purpose built flume. Three important results emerged.
