|CWR Presents : Periodically driven circulation near the shore of a lake
Solutions are found for a linear model of the circulation near the shore of a lake that is subject to two diurnal forcing mechanisms.
The first is the day/night heating/cooling induced horizontal pressure gradients.
The second is an unsteady surface stress modelling a sea breeze/gully wind pattern.
The two forcing mechanisms can oppose or reinforce each other depending on their relative phase. The interplay of different dynamic balances at different times and locations in the domain lead to complex circulation patterns especially during the period of flow reversal.
The solutions to the linear problem are compared with recent and more general numerical solutions of a more complete model.
Duncan graduated with a first class honors in applied mathematics from University of Adelaide in 1986. He went on to study a for a PhD at the CWR under the supervision of John Patterson where he used a combination of analytical and numerical methods to examine unsteady natural convection phenomena in lakes.
After completing his PhD in 1992 Duncan took up a post-doctoral position at the University of Adelaide working with Ernie Tuck working on free surface problems associated with ship hydrodynamics. From 1993 to 1995 Duncan worked in a post-doctoral position in the Department of Mathematics at the University of East Anglia working with David Stevens and John Johnson on numerical methods for Ocean General Circulation Models. Since 1996 Duncan has been an academic in the Mathematics & Statistics program at Murdoch University.
