METHOD FOR DETERMINING SPEED OF THERMO-CAPILLARY FLOW NEAR SIDE SURFACE OF WASHER-SHAPED VIAL Russian patent published in 2007 - IPC G01P5/20 G01F1/704

Abstract RU 2294541 C1

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.
