Paper on Slip: read on Langmuir
Our paper on slip of complex droplets on smooth surfaces is online. Check it out here. Feel free to contact me if you do not have access to the full text. Abstract: The spreading of axisymmetric viscoplastic droplets extruded slowly on glass surfaces is studied experimentally using shadowgraphy and swept-field confocal microscopy. The microscopy furnishes vertical […]
Viscoplastic Fluids: From Theory to Application in Banff
10th anniversary of Viscoplastic Fluids workshop will be held in Banff this year. The meeting will focus on severalk topics such as thixotropy, shear-banding, multiphase and multi-fluid flows, bubbles, drops & particles, onset of motion and stability, computational methods, exotic fluids, thermally sensitive fluids etc. I will present a talk titled: “Thermo-responsive polymeric solutions: from rheology to applications” more information here. […]
APS-DFD, this November at Boston
APS DFD 68 will be held at Boston this year. I will also give a talk on spreading of complex droplets. Here is the abstract: The spreading of yield stress liquid droplets on a dry surface occurs in a number of applications such as 3D printing. In the current study, the surface-tension-driven spreading of a […]
Droplet 2015, a great idea!
Droplet 2015 will be held this Octoeber in Enschede (the Netherlands). This is a relatively small workshop/conference that brings together the people who work on droplets. Michael Brenner of Harvard, Emmanuel Villermaux of Aix Marseille University and so many others are talking droplets. I will also talk about one of my projects on spreading of […]
Smart Impact
My first paper on controlled impact of droplets has been published in Soft Matter. Do not hesitate to contact me if you want a copy. Here is the abstract: A novel methodology for controlling the spreading of droplets impacting a substrate is presented. The working fluid is a thermo-responsive polymer solution that undergoes a sol–gel […]
