We offer the technique of visualization of the pressure fluid flows structure in geometrical discontinuities of the round pipelines (contractions, enlargements, bends and their combination). Flow lines are defined by fast pace cine- and photo shooting. Fluid speeds are specified by the laser Doppler anemometer.
Thin flat pack of the clear fluid flow in any axial area of the round pipe, which contains geometrical heterogeneity, with transparent walls is visualized by flat light flux introducing the suspension of aluminum powder into the flow.
Wedeveloped the device for flat light flux formation.
study of the fluid flows structure in round pipelines;
during the visualization of the fluid flows structure no extraneous elements are introduced into the flow;
research cost is cheaper in comparison with the counterparts.
receiving the real information about the flow structure in the geometrical heterogeneities of the round pipelines; fixing the problem of disturbance of the investigated flow structure with gauges.
experimental study of the flow structure in geometrical heterogeneities of the round pipelines.
