Tunable capillary-induced attraction between vertical cylinders.
Deformation of a fluid interface caused by the presence of objects at the interface can lead to large lateral forces between objects. We explore these fluid-mediated attractive force between partially submerged vertical cylinders. Forces are experimentally measured by slowly separating cylinder pairs and cylinder triplets after capillary rise is initially established for cylinders in contact. F...
متن کاملCapillary rheometry of polymer melts – Simulation and experiment
This paper discusses shear viscosity measurements of polymer melts by the capillary rheometer. Particular emphasis is placed on investigating the effects of viscous heating and pressure dependence of viscosity in capillary flows. The capillary flow problem is addressed by means of numerical simulation using the finite element method to solve the equations of continuity, momentum and energy alon...
متن کاملOn Cylindrical Container Sections for a Capillary Free-Surface Experiment
Small changes in container shape or in contact angle can give rise to large shifts of liquid in a microgravity environment. These shifts can be used as a basis for accurate determination of contact angle. We describe container shapes, designed for a forthcoming USMG2 experiment, in the form of a circular cylinder with two diametrically opposed “canonical proboscis” protrusions. Computational st...
متن کاملTwo Politicians in a Realistic Experiment: Attraction, Discrepancy, Intensity of Delivery, and Attitude Change1
The leader of the Socialists in the Dutch Parliament and his Liberal opponent participated in this realistic experiment. Identical TV interviews with the two politicians were recorded and shown to subjects of both parties. The intensity of delivery was also varied: emotional versus rational. Our findgins indicated that the experimental interveiw changed the attitude of the subjects. In addition...
متن کاملExploring the basins of attraction of tapping mode atomic force microscopy with capillary force interactions
We numerically explore the nonlinear dynamics of the oscillating cantilever tip in tapping mode atomic force microscopy. The cantilever dynamics are determined by complex force interactions between the sample surface and the oscillating cantilever tip which are dominated by attractive, adhesive, and repulsive contributions depending on the instantaneous position of the cantilever. We use a mode...
