DESCRIPTION OF WORK:
The aim of this project is to improve our understanding of seismic and acoustic signals created by gas transport in magmatic systems, with particular emphasis on strombolian systems. The project will provide fluid-dynamic insights into the sub-surface source processes responsible, building on previous work by considering the effect of conduit geometry and inclination, combined with rheological heterogeneities. The ascent of gas through magma will be explored by analogue laboratory experiments where large, individual bubbles rise through a range of liquids including water, oils and silicone compounds. Measurements will include fluid pressures in and above the liquid and the dynamic forces imparted on the apparatus. The fluid dynamics will be modelled using computational fluid dynamics software enabling the results of the experiments to be scaled up to magmatic systems. Coupling of fluid flow to ground and atmospheric motion will be carried out during secondments to other institutions.
WORKING ENVIRONMENT:
The successful Early Stage Researcher (ESR) will initially work in the Physical Volcanology Laboratory, Lancaster Environment Centre, Lancaster University. LEC hosts an active and diverse Volcanology programme with both research and teaching components. The ESR will have full access to training courses and academic modules at undergraduate and postgraduate levels. The candidate will also spend at least one month per year at another of the 13 institutions from 8 countries that form the NEMOH network. Likely secondments are to Dublin and Pisa, to gain additional breadth in numerical modelling techniques.
