Developments and Opportunities Related to High-Order Methods and Aerodynamic Shape Optimization
Speaker: David Zingg, University of Toronto
Presentation
Abstract
This talk will present some recent developments in two areas: 1) multidimensional summation-by-parts (SBP) operators on simplices, and 2) exploratory aerodynamic shape optimization. A definition is given for multidimensional SBP finite-difference operators that extends the classical one-dimensional definition. Examples of such operators are constructed on the triangle and tetrahedron, and numerical results are provided to demonstrate the accuracy and time stability of the simplex operators. In the second portion of the talk, exploratory aerodynamic shape optimization is applied to a regional-class blended-wing body (BWB) aircraft configuration. A shape results that is quite distinct from the typical BWB geometry. Contrary to conventional wisdom it is shown that drag reductions are possible through the BWB configuration even in the regional class.
Biography
David Zingg has been a Professor at the University of Toronto Institute for Aerospace Studies (UTIAS) since 1988 and has been the Director of UTIAS since 2006. His research areas include aerodynamics, computational fluid dynamics, and aerodynamic shape optimization. His current research is focussed on applying high-fidelity aerodynamic shape optimization to the design of novel aircraft configurations motivated by the need to reduce greenhouse gas emissions from aircraft. Together with Harv Lomax and Tom Pulliam from NASA, he is a co-author of the textbooks Fundamentals of Computational Fluid Dynamics, published by Springer in 2001, and Fundamental Algorithms in Computational Fluid Dynamics, published by Springer in 2014. Dr. Zingg held a Tier 1 Canada Research Chair in Computational Aerodynamics and Environmentally Friendly Aircraft Design from 2001 to 2015 and was awarded a Guggenheim Fellowship in 2004.
