Development and application of a novel PIC method to Fluid-structure interactions
Qiang Chen
PhD Research Programme in Civil Engineering, University of Bath
Abstract
With increasing computing power, Computational Fluid Dynamics (CFD) modelling has been considerably developed in many research areas. This work is motivated by developing a hybrid method for numerical modelling of fluid-structure interaction in the coastal and offshore engineering environment. In particular, this is based on the Particle-In-Cell (PIC) method where both particles and grid are utilised. While the particles are used for tracking free surfaces and solving the nonlinear advection term of the Navier-Stokers equations in a Lagrangian manner, the underlying grid is employed for solving the rest non-advection parts in an Eulerian sense. The idea being that the method should have both the flexibility and efficiency from pure Lagrangian methods (based on particles) and Eulerian methods (based on grid), respectively, with a reasonable accuracy.
Biography
Qiang obtained his Master Degree at Dalian University of Technology, China. He is now a PhD student of Dr Jun Zang at the WEIR research unit.
Assessment and mitigation of storm runoff loads from an informal settlement (slum)
Olivia Cooke
PhD Research Programme in Civil Engineering, University of Bath
Abstract
One of the biggest global health problems today is that posed by urban conditions, most significantly in informal settlements. Within informal settlements, the lack of infrastructure including sanitation and sewage facilities can generate serious problems for health and the environment. Stormwater runoff influences these issues and it is necessary to understand the processes and characteristics of runoff to mitigate health risks from it. The aim of this PhD is to develop a scientific theory which determines how stormwater runoff, quality and quantity, is influenced by human and environmental factors, focussing on the case study of the informal settlement Enkanini, located in South Africa.
Biography
Olivia is a PhD Student on the WISE CDT based at the University of Bath in the Department of Architecture and Civil Engineering. She is part of both the Water, Environment and Infrastructure Resilience (WEIR) research group and the Water Innovation and Research Centre (WIRC). Olivia studied Geography under an Open Scholarship at Aberystwyth University and gained a First Class (Honours) BSc. During her third year, Olivia studied for a term at UNIS in Svalbard in the Arctic. Her post-graduate study was a Master of Research in The Science of Natural Hazards at the University of Bristol. Fieldwork included studying the natural hazards in Guatemala, followed by research in Ecuador for her dissertation on volcano risk at Cotopaxi Volcano. Olivia is currently in her second year of her PhD.
Olivia's supervisors are Dr Lee Bryant, Dr Thomas Kjeldsen and Dr Wesaal Khan (Stellenbosch University)
