Blaise Pascal in the 1600s contributed some of the initial theory to this field. The term originates from the work of Daniel Bernoulli, based on the title of his work called Hydrodynamica (1738). He and Leonhard Euler established the general equations of hydrodynamics.
The practice was continued by Joseph Louis Lagrange (1736-1813) with the Euler-Lagrange system, Jean le Rond d'Alembert (1717-1783) discovered the Cauchy-Riemann equations , Pierre Simon Laplace (1749-1827) with the governing equation in the potential flow named after him, Hermann Ludwig Ferdinand von Helmholtz (1821-1894) and William Thomson, Lord Kelvin (1824-1907) with Kelvin-Helmholtz instability (see also Rayleigh-Taylor and Richtmyer-Meshkov) and Helmholtz's work on vortices.
Oscillations are thought to begin from instabilities in the bubble wake, and are observable in both the trajectory and shape.
Bubble hydrodynamics measurements generally consist of making single bubbles through a capillary tube, and video imaging (high speed or normal video camera) followed by computer digitization and analysis.
Perhaps the most important is to control for surfactants, either by using distilled water, by using a known dilute surfactant solution (e.g., sodium dodecyl sulfate) or choosing a specific water (such as lake, sea, etc.).
Hydrodynamics International was formed through a joint venture between Superior Growers Supply, Inc. and West Australian company, Growth Technology Ltd. with the purpose of marketing successful European and Australian products into the North American market.
We appointed the leading companies in the field as our subdistributors and thus were able to achieve the broadest level of market coverage in the industry.
Hydrodynamics actively strives to promote the excellence of its products through involvement with trade magazines, displays at trade shows, and developing relationships with store owners nationwide.
