A Surface-tension Experiment

Long-wavelength surface-tension-driven Bénard convection: experiment and theory

Surface-tension-driven Bénard (Marangoni) convection in liquid layers heated from below can exhibit a long-wavelength primary instability that differs from the more familiar hexagonal instability associated with Bénard. This long-wavelength instability is predicted to be significant in microgravity and for thin liquid layers. The instability is studied experimentally in terrestrial gravity for ...

The gas-liquid surface tension of argon: a reconciliation between experiment and simulation.

We present a simulation of the liquid-vapor interface of argon with explicit inclusion of the three-body interactions. The three-body contributions to the surface tension are calculated using the Kirkwood-Buff approach. Monte Carlo calculations of the long-range corrections to the three-body contribution are calculated from the radial distribution function g((2))(z1, cos θ12, r12). Whereas the ...

Surface Tension of Serum

An attempt was made to apply to the study of immune sera the fact, pointed out in our previous papers, that at a given dilution the serum shows a maximum drop of surface tension in function of time (time-drop). The results of the experiments here reported would seem to indicate that: 1. The time-drop of a serum solution is greater after the animal has been immunized than before immunization (fr...
