Density oscillator

Dependence of oscillation frequency on the surface area at a single system

Abstract

The frequencies of a density oscillator which consists of two containers filled with fluids of different densities were measured by a laser light method, where both the fluids were contacted through a small orifice on the bottom of the inner container It was found that the frequencies of the oscillation increased with decreasing the surface area of the outer container filled with pure water and that the stable oscillation of the flow ceased beyond a critical value of the surface area of the water container as decreasing the free surface area of water.
