How molecular effects affect solutal Marangoni convection
Petter Johansson, Guillaume Galliéro, Dominique Legendre
Interfacial tension gradients drive flow along liquid-liquid interfaces in a process known as the Marangoni effect. Such gradients can be caused by surfactants, which has been exte…
Steady moving contact line of water over a no-slip substrate
Uǧis Lācis, Petter Johansson, Tomas Fullana +4
The movement of the triple contact line plays a crucial role in many applications such as ink-jet printing, liquid coating and drainage (imbibition) in porous media. To design accu…
Electrowetting diminishes contact line friction in molecular wetting
Petter Johansson, Berk Hess
We use large-scale molecular dynamics to study dynamics at the three-phase contact line in electrowetting of water and electrolytes on no-slip substrates. Under the applied electro…
Molecular Origin of Contact Line Friction in Dynamic Wetting
Petter Johansson, Berk Hess
A hydrophilic liquid, such as water, forms hydrogen bonds with a hydrophilic substrate. The strength and locality of the hydrogen bonding interactions prohibit slip of the liquid o…
A Ronkin type function for coamoebas
Petter Johansson, Håkan Samuelsson Kalm
The Ronkin function plays a fundamental role in the theory of amoebas. We introduce an analogue of the Ronkin function in the setting of coamoebas. It turns out to be closely relat…
On the order map for hypersurface coamoebas
Jens Forsgård, Petter Johansson
Given a hypersurface coamoeba of a Laurent polynomial f, it is an open problem to describe the structure of its set of connected complement components. In this paper we approach th…
