The Marangoni instability of a horizontal binary mixture layer with a deformable free surface and a solid substrate is investigated under the action of a modulated heat flux. In contrast to the case of a homogeneous liquid, due to thermal diffusion (Soret effect), the modulation of the heat flux creates not only a temperature wave in the layer, but also a concentration wave, which change a surface tension. The modulation of the heat flux with a zero mean value is considered in two cases: i) on free surface, ii) on a rigid bottom boundary. In both cases, the long-wave instability exists within the established frequency intervals. The dependences of the critical Marangoni number and the corresponding modulation frequency on the separation ratio and the Lewis number are obtained for long-wave disturbances. The fundamental features of the case (i), as compared to the case (ii), are as follows: the instability domains are located in the lower frequency ranges and the minimum Marangoni number is several times smaller.

We investigate trajectories of microscale evaporating droplets in a stagnation point flow near a wall of a respiratory airway. The configuration is motivated by the problem of advection and deposition of microscale droplets of respiratory fluids in human airways during transmission of infectious diseases such as tuberculosis and COVID-19. Laminar boundary layer equations are solved to describe the air flow while the equations of motion of the droplet include contributions from gravity, aerodynamic drag, and Saffman force. Evaporation is accounted for at both the droplet surface and the wall of the respiratory airway and is shown to delay droplet deposition as compared to the predictions of isothermal models. Evaporation at the airway wall has a stronger effect on droplet trajectories than evaporation at the droplet surface, leading to droplets being advected away by the flow and thus avoiding deposition in the stagnation point flow region.

The present study investigates the role of thermophysical and electrical properties of various liquid drops on their continuous motion over a PDMS coated electrode with water as a reference. Droplet motion is achieved in an electric field around an active electrode when a ground wire is placed horizontally in an open-EWOD device. A CCD camera is used to record the drop shapes and displacement of the moving droplet at 120 fps. Using image processing tools, the velocity of the droplet is determined from a time sequence of its centroid position. The dynamic contact angle of the drop is determined from the tangent drawn over the air-liquid interface. Liquids of interest include ferrofluid and a surfactant solution in water as well as glycerin for droplet volumes in the range of 2-10 µl with voltages within 170-270VDC. Simulations are carried out in a 2D Cartesian coordinate system within COMSOL Multiphysics® software. The drop is taken to spread immediately after application of voltage following the Young-Lippmann equation and is accompanied by continuous motion. The interfacial forces arising from the electric field are calculated in terms of the Maxwell’s stress tensor (MST). The electrostatic force is source term in the Navier-Stokes equations using a fully coupled approach. Interface shapes of ferrofluid and surfactant droplets do not show significant departure from moving water droplets. As the concentration of the ferrofluid increases, surface tension decreases, and the droplet speed increases. The extent of spreading of a surfactant solution is higher, thus generating a higher interfacial area for the electric field, leading to a higher droplet velocity. Continued.

Effect of rotational velocity modulation on the shape of the interface between liquids with high contrast of viscosities and of different densities, in a rapidly rotating horizontal cylinder is experimentally investigated. During rotation, the more viscous fluid with higher density is located near the lateral boundary of the cavity. It is found that modulation of the rotation rate leads to the loss of stability of the initially axisymmetric liquid-liquid interface. The instability manifests itself in the development of spatially periodic quasi-stationary 2D relief on the interface. The phenomenon has a threshold character; the critical amplitude of velocity modulation depends on the rotation rate and the frequency of velocity modulation. It is shown that the appearance of the "frozen" relief is associated with the Kelvin—Helmholtz oscillatory instability and is accompanied by the generation of intensive vortex flows near the interphase boundary.
