СПОСОБ ОПРЕДЕЛЕНИЯ СКОРОСТИ ТЕРМОКАПИЛЛЯРНОГО ТЕЧЕНИЯ У БОКОВОЙ ПОВЕРХНОСТИ ШАЙБОВИДНОГО ПУЗЫРЬКА

摘要

FIELD: possible use for diagnostics of flow of liquids in the channel of micro-fluid pump or optical switch. ^ SUBSTANCE: in accordance to method, thermo-capillary flow is excited by means of a light beam. Static curvature and total curvature of visually observed side surface of washer-shaped vial are measured, deformation of which surface is caused by thermo-capillary flow. On basis of results of measurement, speed of the flow is determined. ^ EFFECT: simplified diagnostics of current in micro-scale. ^ 5 dwg
