Numerical Uncertainty in Computational Fluid Dynamics and Computational Nanoscience Professor Dimitris Drikakis, FRAeS, FIoN Head of Aerospace Sciences Department Cranfield University, School of Engineering Cranfield, Befordshire, MK43 0AL, United Kingdom Tel: +44-1234-754796, Secretary Tel Extension: 750111 (Ext 5010), Fax: +44-1234-758207, E-mail: d.drikakis@cranfield.ac.uk Abstract: The talk concerns issues of numerical uncertainty in computational fluid dynamics and computational nanoscience. It presents the sensitivity of complex physics such as turbulence and micro/nano scale phenomena, to the initial and boundary conditions, and order of numerical accuracy. Theoretical developments and results from practical applications featuring shock waves, transition and turbulence, and multi-scale phenomena at the interface of continuum and molecular mechanics, are presented. About the Speaker: Professor Dimitris Drikakis is the Head of the Department of Aerospace Sciences in the School of Engineering at Cranfield University. Prior to that he was Professor of Fluid Mechanics at Queen Mary, University of London. His research interests include: computational methods, aerodynamics; turbulent flows; s hock physics; nanotechnology; microfluidics/nanofluidics; biomedical flows, instabilities. He has extensive experience in the development and application of high-resolution, CFD methods. He has published over 130 journal and conference papers, as well as several invited chapters in books. Further, he has published a CFD textbook on High-Resolution Methods for Incompressible and Low- Speed Flows (jointly with Bill Rider, Los Alamos National Lab, USA), Springer Verlag (2004) , and an edited book (jointly with Bernard Geurts, Twente Univ., the Netherlands) on Turbulent Flow Computations, Kluwer Academic Publishers (2002).
