Apparatus for the optical observation of the mixing phenomena caused by the instability between two fluids

摘要

the apparatus allows for the study of the mixing of a fluid and a light fluid is subjected to a heavy acceleration, due to instabilities occurring at the interface.the fluid is contained in a first volume (16) of an observation chamber (9, 10) and are separated by a diaphragm (11).;the invention is designed to remove as soon as possible the diaphragm (11) at the beginning of the experiment.the extraction is done after pressure in the sealed chamber (1) of the lock shaft (24), a sudden movement of the axis by means of a piston (26) under high pressure.;the apparatus includes the experimental conditions of the study of "taylor instability.
