Abstract
An experimental investigation of the study for pulsed particle visualization of micro tracers using the PIV technique was conducted. The purpose of the study was to obtain the velocity distribution in straight and turns of the pipeline and influence of different geometries of the inserts (swirlers) on the cause of the pressure gradient on the outer and inner walls of the parts. The visualization of fluid flow consisting tracer particles was determined. In order to study the flow pattern a design of passive devices was performed and put into experimentation to investigate the flow field. The PIV-technique and equipment allow the analytical study of the microstructure for hydrodynamic fluid flow and the measurement of piping vibration after passing through the passive damper. It was found that the use of the improved devices leads to the reduction of piping vibration at 25–50%. It was possible to figure out the velocity distribution pattern as well as the visualization of the swirling of the fluid flow based on PIV technique.
