Prof. Dr. Clinton Groth - Parallel Adaptive Mesh Refinement Schemes for Multi-Scale Physically-Complex Flows with Application

Institute for Aerospace Studies, University of Toronto


Although there have been significant advances in both numerical methods, and high-performance computing systems for large-scale scientific computing applications, including computational fluid dynamics, over the past 10-15 year, there remain a variety of multi-scale, physically-complex flow problems, which are still not well understood and have proven to be very challenging to predict by computational means. Such flows would include but are not limited to: (i) turbulent and reactive flows encountered in advanced propulsion systems; (ii) compressible flows of conducting fluids and plasmas; and (iii) micro-scale and/or rarefied non-equilibrium flows among others. A class of highly-scalable, parallel, adaptive mesh refinement, high-order, finite-volume schemes are proposed for the solution of multi-scale physically-complex flows on body-fitted multi-block mesh. Details of the high-order spatial and temporal discretization meethods and local solution-dependent refinement strategies will be discussed. Applications of the solution methods to laminar and turbulent reactive flow and space plasma flow problems will also be described in order to demonstrate the capabilities and performance of the proposed methodology.
