Numerical Simulation of a Cryogenic Spray
… study is to document such characteristics. The numerical simulation was performed over cryogenic nitrogen spray using an Eulerian-Lagrangian approach. In other words, while the gas phase of the flow is treated as a continuum, the nitrogen droplets are tracked individually in a Lagrangian sense. …

Numerical Simulation of Ginzburg-Landau Equations
<p>We introduced two methods to discretize the Ginzburg-Landau equations with the help of link variables. With these equations, we build models to simulate the mixed state of type-II superconductivity. We successfully get Abrikosov vortices by solving both in 2D cases and 3D cases. This tells us …

Numerical simulation of the casting process
… cost-effective development method is required. Numerical modelling techniques provide a means by which casting design and process parameters can be optimized with minimum use of prototypes. This thesis reviews the current state of the art in solidification modelling. A typical casting problem is …

Numerical simulation of primary petroleum migration
A numerical simulation is presented for the generation and movement of petroleum in a single layer of source rock, a process also know as primary migration. The equations governing the system are derived from principles of mass and volume conservation and are then non-dimensionalized. The result of …

Numerical Simulation on Dilute Phase Pneumatic Transport
Pneumatic conveying is a technique that is widely used in many industrial mechanical and chemical applications. In the case of cement manufacturing pneumatic conveying is a large scale operation moving several kilograms of material per second which consumes electrical energy (operation of fans) and …

The numerical simulation of non-supercell tornadogenesis
Non-supercell tornado is a name given to a class of tornadoes which occur with deep moist convection not displaying the strong mid-level rotation found in supercell thunderstorms. In recent years the severe storms community has acknowledged that a significant portion of the small tornadoes …

Direct numerical simulation of droplet-laden isotropic turbulence
… goal of this work is to investigate using direct numerical simulation (DNS) the physical mechanisms of droplet-turbulence interaction, both for non-evaporating and evaporating droplets. To achieve this objective, we develop and couple a new pressure-correction method with the volume-of-fluid (VoF) …

Analysis and numerical simulation of tumor growth models
In this dissertation we focus on the numerical analysis of tumor growth models. Due to the difficulty of developing physically meaningful approximations of such models, we divide the main problem into more simple pieces of work that are addressed in the different chapters. First, in Chapter 2 we …
