Summary of Activities/Interests
There is an ever-growing concern for the impact we have on the earth and its resources. As such, it has become critical to study and understand the influence of our actions so as to minimize negative impacts and continue to fruitfully exploit the resources available. Motivated by this and his personal passion for fluid dynamics, most of Dr. Bolster's research to date has concerned the study of environmental fluid flows and contaminant transport across a wide range of scales and scenarios from groundwater flows in porous media, to confined buoyancy-driven flows in enclosed spaces such as buildings to larger scale buoyancy-driven atmospheric flows such as gravity currents.
In most projects, Dr. Bolster has developed simple mathematical and numerical models in the hope of providing useful and useable tools to practitioners and policy makers for whom such tools are essential for effective decision-making. He has also run laboratory scale experiments to obtain further insight into the physical phenomena taking place and to verify the models he developed.
The specific areas of research in which Dr. Bolster works include: contaminant transport in coastal aquifers, multiphase flow and reactive contaminant transport in heterogeneous porous media (with potential applications to CO2 sequestration), pore scale modeling of contaminant transport, probabilistic risk assessment relating to contamination scenarios, intrusive gravity currents, transient flows in naturally ventilated spaces, contaminant transport in lo- energy buildings and vortex rings.
