Direct numerical simulations of turbulent non-rotating and rotating plane Couette flow with a periodically modulated plate velocity are conducted to study the effect of modulated forcing on turbulent shear flows. The time-averaged shear Reynolds numb

There is considerable interest in high fidelity simulation of both single phase incompressible flows and multiphase flows. Most commonly applied numerical methods include finite difference, finite volume, finite element and spectral methods. All of t

Multi-modal film boiling simulations are carried out on adaptive octree grids. The liquid-vapor interface is captured using the volume-of-fluid framework adjusted to account for exchanges of mass, momentum, and energy across the interface. Surface te

A three-dimensional numerical study is conducted of a single FC-87 vapor bubble rising in non-uniformly heated FC-87 liquid and interacting with an inclined superheated wall. A complete phase-change model that takes into account the effect of interfa

New measures of Digital Thermal Monitoring (DTM), a low cost non-invasive tool to assess vascular health, are developed. Original measures of thermal vascular reactivity tend to be dependent upon the initial vascular state (such as temperature before

Sliding bubbles are known to augment heat transfer rates on the surface on which they slide. The pre-cursor problem — the bubble approaching an inclined superheated wall provides the initial flow and thermal field for the sliding bubble problem. An

In checking the fitness of fatigue critical welded structure, the stress concentration at the weld due to the weld geometry needs to be considered. Where fatigue is assessed using crack growth methodology, two approaches are commonly used. In the off

A methodology is developed to account for the effect of crack face pressure on the reference stress in high pressure, thick walled, flowlines and risers. Risers and flowlines in production service may be exposed to corrosive attack resulting in pitti
