A computational study of particulate emissions from Old Moor Quarry, UK (2017)
Journal Article
Joseph, G., Lowndes, I., & Hargreaves, D. (2018). A computational study of particulate emissions from Old Moor Quarry, UK. Journal of Wind Engineering and Industrial Aerodynamics, 172, 68-84. doi:10.1016/j.jweia.2017.10.018

This paper presents an evaluation of a buoyancy-modified k--e dust dispersion model for predicting fugitive dust deposition from a surface quarry. The dust clouds are modelled as volumetric emissions and their dispersion simulated by coupling the flo... Read More

Pore-scale numerical investigation of pressure drop behaviour across open-cell metal foams (2017)
Journal Article
Carvalho, T. P. D., Morvan, H., Hargreaves, D., Oun, H., & Kennedy, A. (2017). Pore-scale numerical investigation of pressure drop behaviour across open-cell metal foams. Transport in Porous Media, 117(2), doi:10.1007/s11242-017-0835-y. ISSN 0169-3913

The development and validation of a grid-based pore-scale numerical modelling methodology applied to five different commercial metal foam samples is described. The 3-D digital representation of the foam geometry was obtained by the use of X-ray micro... Read More

Numerical modelling of the rise of Taylor bubbles through a change in pipe diameter (2017)
Journal Article
Ambrose, S., Lowndes, I. S., Hargreaves, D., & Azzopardi, B. (2017). Numerical modelling of the rise of Taylor bubbles through a change in pipe diameter. Computers and Fluids, 148, doi:10.1016/j.compfluid.2017.01.023. ISSN 0045-7930

The rise of Taylor bubbles through expansions in vertical pipes is modelled using Computational Fluid Dynamics. The predictions from the models are compared against existing experimental work and show good agreement, both quantitatively and qualitati... Read More

Numerical modeling of oscillating Taylor bubbles (2016)
Journal Article
Ambrose, S., Hargreaves, D., & Lowndes, I. (in press). Numerical modeling of oscillating Taylor bubbles. Engineering Applications of Computational Fluid Mechanics, 10(1), doi:10.1080/19942060.2016.1224737. ISSN 1997-003X

In this study, computational fluid dynamics (CFD) modeling is used to simulate Taylor bubbles rising in vertical pipes. Experiments indicate that in large diameter (0.29 m) pipes for an air–water system, the bubbles can rise in a oscillatory manner,... Read More

Computational studies on pressure distribution around a bending 5:1 rectangular cylinder (2016)
Conference Proceeding
Nguyen, D. T., Hargreaves, D., & Owen, J. (2016). Computational studies on pressure distribution around a bending 5:1 rectangular cylinder

This paper describes the development and testing of a numerical model, based around the Large Eddy Simulation model, of a flexible 5:1 rectangular cylinder. We report on the vortex-induced vibration (VIV) of the bending cylinder, which is an analogue... Read More

This paper presents a numerical method based on a LES approach to modelling the unsteady flow around and the vortex-induced vibration (VIV) of a 5:1 rectangular cylinder in the smooth and turbulent flow. A fluid-structure interaction algorithm was al... Read More

Bridge deck flutter derivatives: efficient numerical evaluation exploiting their interdependence (2014)
Journal Article
Nieto, F., Owen, J., Hargreaves, D., & Hernández, S. (2015). Bridge deck flutter derivatives: efficient numerical evaluation exploiting their interdependence. Journal of Wind Engineering and Industrial Aerodynamics, 136, doi:10.1016/j.jweia.2014.11.006. ISSN 0167-6105

Increasing the efficiency in the process to numerically compute the flutter derivatives of bridge deck sections is desirable to advance the application of CFD based aerodynamic design in industrial projects. In this article, a 2D unsteady Reynolds-av... Read More
