Professor Paul Linden is the G.I. Taylor Professor Emeritus of Fluid Mechanics and Director of Research in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge and is also the Blasker Distinguished Professor Emeritus of Environmental Science and Engineering, Department of Mechanical and Aerospace Engineering, UC San Diego.

The challenge of simulating airflow in buildings comes from the unique combination of complex geometry and boundary conditions and the intrinsic dynamics of the air flow, particularly when buoyancy force and convection are important - as they often are. The talk will illustrate this challenge by describing the basic types of ventilation flows and presenting different methods to simulate them. In particular, the possibilities and limitations of various simulation techniques will be discussed and some outstanding issues in airflow simulation described, together with some recent laboratory experiments and simulation results.
