Тема: High-resolution methods and algorithms for multiscale modelling in fluid mechanics: from aerospace to nano-scale flows
Докладчик: Sergey Karabasov

 Multiscale problems are encountered in many areas of unsteady fluid dynamics modelling. For their solution, one typically requires a model which has two key components. One component is a high-resolution computational algorithm for accurately solving unsteady flow equations with a limited number of degrees of freedom. One of such algorithms, the CABARET scheme developed by authors, will be considered and examples of its applications for direct simulation of aeronautical flows will be presented. The other important component is a technique for consistently coupling coarse-scales with fine-scales in space and time that differ by many orders of magnitudes within the same computational framework. For this talk, two topical fluid dynamics applications that require multiscale coupling schemes will be considered. One is the modelling of sound generated by turbulent jet/wing flows in aerospace engineering. The second example is micro/nano-scale flow modelling using Landau-Lifshitz Fluctuating Hydrodynamics (FH) equations which describe thermal fluid fluctuations at nano-scale. For the second application, new approaches for coupling FH model with Molecular Dynamics equations will be also discussed.
