SUBJECT: Call for LIFD Visiting Fellows
Our LIFD Visiting Fellows scheme aims to attract distinguished scholars
from around the world to work with LIFD. Fellows are normally invited to
spend between one and three months at the University of Leeds; longer
stays may also be possible subject to funding. Fellows will have full
library access and IT support, office space in one of our Schools and
will be able to access suitable Laboratories and High Performance
Computing to support their research. We expect Fellows to deliver an
LIFD colloquia talk and we encourage visitors to proactively engage with
our postgraduate students and wider LIFD research activity during their
stay. CLOSING DATE FOR APPLICANTS WISHING TO VISIT BETWEEN 1/11/21 AND
31/7/22: 30/9/21

EVENTS:   

FROM: Claire Savy, University of Leeds, 18/8/21
SUBJECT: Droplet dynamics in the presence of gas nanofilms: merging,
wetting, bouncing & levitation. Professor James Sprittles is a Professor
in the Mathematics Institute at the University of Warwick who is
interested in the computational modelling of small scale flows.  His
recent fundamental research has focussed on the influence of gas kinetic
effects and thermal fluctuations on droplet dynamics, with more applied
interests in multimaterial 3D printing and thermal management. Recent
advances in experimental techniques have enabled remarkable discoveries
and insight into how the dynamics of thin gas/vapour films can
profoundly influence the behaviour of liquid droplets: drops impacting
solids can "skate on a film of air" [1], so that they can "bounce off
walls" [2,3]; reductions in ambient gas pressure can suppress splashing
[4] and initiate the merging of colliding droplets [5]; and evaporating
droplets can levitate on their own vapour film [7] (the Leidenfrost
effect). Despite these advances, the precise physical mechanisms
governing these phenomena remains a topic of debate.  A theoretical
approach would shed light on these issues, but due to the strongly
multiscale nature of these processes brute force computation is
infeasible.  Furthermore, when films reach the scale of the mean free
path in the gas (i.e. ~100nm) and below, new nanoscale physics appears
that renders the classical Navier-Stokes paradigm inaccurate. In this
talk, I will overview our development of efficient computational models
for the aforementioned droplet dynamics in the presence of gas nanofilms
into which gas-kinetic, van der Waals and/or evaporative effects can be
easily incorporated [8,9].  It will be shown that these models can
reproduce experimental observations - for example, the threshold between
bouncing and wetting for drop impact on a solid is reproduced to within
5%, whilst a model excluding either gas-kinetic or van der Waals effects
is ~170% off!  These models will then be exploited to make new
experimentally-verifiable predictions, such as how we expect drops to
behave in reduced pressure environments.  Finally, I will conclude with
some exciting directions for future work.
EVENT DATE: 6/10/21, 14:00 BST
DETAILS: https://bit.ly/3geJhaj  

FROM: Lars Davidson, Flow Sim, 12/8/21
Subject: Large Eddy Simulation (LES), hybrid LES-RANS, Detached Eddy
Simulation (DES) and unsteady RANS. LES is suitable for bluff-body flows
or flows at low Reynolds numbers. To extend LES to cover industrial
flows at high Reynolds numbers, new approaches (hybrid LES-RANS, DES,
URANS, SAS, PANS, PITM) must be used. They are all based on a mix of LES
and RANS. The course will give an introduction to LES and these new
methods. LES, or any of the new approaches, is the first step when
performing accurate CAA (Computational Aero-Acoustics) The lectures will
be given on-line (Live) using Zoom. During the workshops, the
participants will get supervision in a joint Zoom room which will enable
participants to learn from each others questions. Part of the
supervision may also be given in individual break-out Zoom rooms.
Lectures will be given in the mornings; in the afternoons there will be
workshops using Python (recommended), Matlab or Octave. The participants
must have a PC/Mac/Desktop with one of these software installed. In the
workshops, the participants will use Python/Matlab/Octave for analyzing
analyzing SGS models, SAS, PANS, DES and DDES. Scripts will be use for
generating isotropic and anistropic (non-isotropic) synthetic turbulent
fluctuations for inlet boundary conditions and embedded LES.
