Lecture: "Numerical Modeling of Turbulent Flows with OpenFOAM for Engineering Applications"
Abstract: In this training session we shall review the theoretical background, numerical implementation and practical use of turbulence modelling in modern industrial CFD. The lecture will review the aspects of practical Direct Numerical Simulation, RANS-based turbulence modelling and Large Eddy Simulation in industrial practice.
Lecture: "Turbulence as a meeting place"
Abstract: Turbulence is a vast field, where mathematicians, physicists and engineers meet astrophysicists and meteorologists. Each discipline brings its own unique perspective into studies of turbulence. What is a nuisance to be eliminated for an engineer could be a source of fascination for a physicist. The most difficult aspect of cross-discipline interaction is mutual understanding of motivations. In this lecture, a physicist will present his view on turbulence and describe several cross-field interactions.
Lecture: "Some Aspects of the Past, Present and (perhaps) the Future"
Abstract: Despite its ubiquity in nature and technology, turbulence remains a paradigmatic challenge for non-equilibrium statistical mechanics. This challenge is closely related to the nonlinear, non-local and dissipative character of the underlying equations of motion which withstand most concepts that modern physics has developed so far. The rapid evolution of computational power and experimental techniques, however, has brought significant progress over the past decades by allowing unprecedented insights into the structure and dynamics of turbulence.
In this short course, the participants will be introduced to the phenomenon of turbulence as a complex system that can be treated with methods from non-equilibrium statistical mechanics. Classical phenomenologies such as the Kolmogorov theory will be presented along with first-principle statistical approaches starting from the Navier-Stokes equation. The theoretical results and predictions will be confronted with recent numerical and experimental results. Finally, we will discuss how joint experimental, numerical and theoretical efforts may be combined to make progress in this long-standing problem.
Lecture: "Measurements of the dynamics of turbulent fluid flows using tracking of tracer and complex particles"
Training: "Multi-camera measurement techniques in turbulent flows"
Abstract: The lecture will track the history of particle tracking experiments from Richardson through recent measurements where enough particles are tracked to reveal the full space-time velocity field in 3D turbulence. The focus will be on the insights into the dynamics of turbulent fluids that have been obtained including dispersion, fluid accelerations, Lagrangian structure functions and velocity gradient dynamics in a Lagrangian frame. Then we will explore motion of more complex particles such as inertial particles, spheres larger than the Kolmogorov scale, fibers, disks, and other non-spherical shapes including tetrads and chiral dipoles. The training session will be an interactive exploration of issues involved in designing turbulent flow facilities and measuring fluid flows using multi-camera methods. We will discuss the state of the art in imaging hardware, camera calibration models, and image analysis methods. Particular focus will be on 3D particle tracking methods with comparisons to stereoscopic PIV, Tomo-PIV and holographic particle tracking. We will also discuss some of the challenges of designing flow facilities and some of the real-world properties of turbulent flows such as facility scale modes and large scale intermittency that always exist but are not always accounted for.
