LIFD member session: EPSRC responsive mode funding , opportunities and experiences About this event We are pleased to invite you to virtually join us on the 8th October 2021, 10.00am-11.00am, for a brief update on the latest progress and upcoming activities for LIFD, followed by an introduction to EPSRC responsive mode grants available, and a…
LEEDS INSTITUTE FOR FLUID DYNAMICS: Virtual Colloquium About this event Speaker: Professor James Sprittles, Mathematics Institute, University of Warwick Title: Droplet dynamics in the presence of gas nanofilms: merging, wetting, bouncing & levitation Bio: James Sprittles is a Professor in the Mathematics Institute at the University of Warwick who is interested in the computational modelling of small scale…
New report indicates UK Fluid Dynamics contributes £14 billion to UK economy About this event The UK Fluids Network and Leeds Institute for Fluid Dynamics (LIFD) are hosting a launch event for a new report which for the first time details the current value of fluid dynamics to the UK. Fluid Dynamics is the study…
LEEDS INSTITUTE FOR FLUID DYNAMICS: Virtual Colloquium About this event Speaker: Alison Stirling, Met Office Title: Modelling atmospheric convection for meteorological prediction Bio: Alison joined the convection group at the Met Office having obtained a degree in theoretical physics from the University of Cambridge and a PhD in astronomy from the Institute for Astronomy at…
Speaker: Guohua Wang, Lanzhou University, China Date/Time: Friday 18th June 2021 4:00pm BST/11am EDT Title: Very-large scale motions in the atmospheric surface layer Abstract: Very-large scale motions (VLSMs) are typical structures in wall-bounded turbulence at high Reynolds number, which make important contributions to mass and energy transport. This talk will present the atmospheric surface layer observations carried out at…
Speaker: Jane Bae, Harvard University, USA Date/Time: Friday 11th June 2021 4:00pm BST/11am EDT Title: Nonlinear interaction of the self-sustaining process in the near-wall region of wall-bounded turbulence Abstract: We investigate the nonlinear interaction in the self-sustaining process of wall-bounded turbulence. Resolvent analysis is used to identify the principal forcing (nonlinear) mode which produces the maximum amplification in direct…
  Speaker: Laura Cope, Cambridge University, UK Date/Time: Friday 4th June 2021 4:00pm BST/11am EDT Title: The dynamics of stratified horizontal shear flows at low Péclet number Abstract: Stratified flows are ubiquitous; examples include atmospheres and oceans in geophysics and stellar interiors in astrophysics. The interaction of a stable stratification with a background velocity distribution can develop into stratified…
Speaker: Chris Howland, University of Twente, Netherlands Date/Time: Friday 28th May 2021 4:00pm BST/11am EST Title: Quantifying mixing in simulations of stratified flows Abstract: Turbulent mixing exerts a significant influence on many physical processes in the ocean. In a stably stratified Boussinesq fluid, this irreversible mixing describes the conversion of available potential energy (APE) to background potential energy (BPE)….
Speaker: Adrian Lozano-Duran, MIT, USA Date/Time: Friday 21st May 2021 4:00pm BST/11am EST Title: Cause-and-effect of linear mechanisms sustaining in wall turbulence Abstract: Despite the nonlinear nature of turbulence, there is evidence that part of the energy-transfer mechanisms sustaining wall turbulence can be ascribed to linear processes. The different scenarios stem from linear stability theory and comprise exponential instabilities,…
Speaker: George Fortune, University of Cambridge, UK Date/Time: Friday 14th May 2021 4:00pm BST/11am EST Title: Waltzing worms: the dynamics of plant-animal collective vortex structures Abstract: Circular milling, a stunning manifestation of collective motion, is found across the natural world, from fish shoals to army ants. It has been observed recently that the plant-animal worm Symsagittifera roscoffensis exhibits circular milling behaviour,…
