We numerically study the dynamics of a passive fluid droplet confined within microchannel whose walls are covered with thin layer active gel. The latter represents fluid...

A method for Monte Carlo studies of phase equilibrium in confined systems is presented using an example of vapor-liquid equilibrium (capillary condensation and evaporation) in cylindrical pores. The method, named the gauge cell method, allows one to construct the full phase diagram of a confined fluid in the form of a van der Waals loop, which includes stable, metastable, and unstable equilibri...

The flow around a tethered cylinder subjected to an incoming flow transverse to its main axis and confined in a channel is investigated by means of global stability analysis of the full coupled body–fluid problem. When the cylinder is strongly confined (ratio of cylinder diameter to cell height, D/H = 0.66) we retrieve the confinement-induced instability (CIV) discovered by Semin et al. (J. Flu...
