This course will address the analysis of modern approaches to turbulence modelling, different models and their applications to the solution of industrial problems including external and internal aerodynamics, heat transfer, combustion, aero-acoustics, Lattice Boltzmann Method, Smooth Particle Hydrodynamics (SPH), waves and tidal energy extraction modelling.
Computational Fluid Dynamics (CFD) is required in many industrial applications including external and internal aerodynamics, heat transfer, combustion, aeroacoustics, etc. It is “therefore”, if not more, at least equally important as experimental fluid dynamics. Nowadays many practical problems require high accuracy of prediction, taking into account different physical effects and coupling different models. The course will address some modern techniques in CFD and their applications to the solution of industrial problems. They target to resolve an inevitable trade-off between the accuracy of prediction and effectiveness of mathematical modelling. The course consists of two parts: a theoretical course on advanced CFD methods and tutorials with open-source “Code_Saturne” for solving the Navier-Stokes equations. The main focus of the first part will be on high-resolution finite-volume methods for convection dominated problems, fluid-structure interaction methods, artificial boundary conditions, resolution of uncertainties, Lattice Boltzmann Method and Smooth Particle Hydrodynamics (SPH).
The second (practical) part of the course will be held at the Hartree Centre, on the campus of the Science & Technology Facilities Council (STFC) Daresbury Laboratory. This part is devoted to learning how to use the open-source CFD solver Code_Saturne, which is developed by EDF R&D for solving the Navier-Stokes equations. Code_Saturne is a co-located finite volume solver capable of handling unstructured meshes. It has a large collection of RANS/LES models with additional modules for compressible flows, combustion, radiative heat transfer, magneto-hydrodynamics, two-phase flows and atmospheric flows. Through various projects, STFC Daresbury Laboratory have tested Code_Saturne's High-performance computing (HPC) capabilities. They also have excellent training and HPC facilities; the Hartree Centre currently hosts 41st and 49th fastest supercomputers in the world (Top500 supercomputers, Nov 2015). This is a very successful course which has been running every year since 2012. It is delivered by the academic staff of the University of Manchester and researchers from STFC. This year there will also be a guest lecture from Professor Brian Launder whose principal research has been in developing and testing models of turbulent momentum and heat transport within the framework of RANS and URANS numerical solvers, particularly in the presence of strong buoyant or rotational forces. His work is documented in his recent research-level textbook with Professor Hanjalic: "Modelling turbulence in engineering and the environment" CUP, 2011. He was elected a Fellow of both the Royal Academy of Engineering and the Royal Society and received the prestigious 2013 Nusselt-Reynolds Prize in recognition of his achievements.
