SUMMARY:Marangoni flows and instabilities during drying - William Schabel\
 , Karlsruhe Institute of Technology
DTSTART:20211007T103000Z
DTEND:20211007T113000Z
UID:TALK162007@talks.cam.ac.uk
CONTACT:Catherine Pearson
DESCRIPTION:Inhomogeneous drying conditions result in Marangoni flows and 
 instabilities with a free-surface deformation. Surface tension of multi-co
 mponent solutions depend on both temperature and composition\, and a local
  inhomogeneous heat and mass transfer lead to mass flow and film defects. 
 In order to investigate the flow field within thin films\, a new measureme
 nt technique (3D μPTV) has been developed. This measurement technique giv
 es unique insights\, which will allow us to identify process parameters cr
 ucial to the surface homogeneity of thin films and printed structures. An 
 overview about former results and new results will be presented with a foc
 us on stability analysis and a critical Marangoni number and new correlati
 on.\n\n\nWe are delighted that the BPI seminars will be delivered in-perso
 n and via Zoom going forward beginning this Thursday\, although limited nu
 mbers able to attend in person.\n\nTo book an in-person seat at the semina
 r this Thursday please use the link below - please note that once the numb
 er is reached you will not be able to register. There will also be a selec
 tion of individually wrapped sandwich lunches for everyone who is attendin
 g in-person.\n\nhttps://stokes.cceif.group.cam.ac.uk:1763/seminarreg/16200

 e AND during the seminar and in all communal areas. Face coverings should 
 only be removed once you have collected lunch and are back at your seat. P
 lease also note that for ventilation windows in the Open Plan Area must re
 main open at all times.
