Research on the flow velocity characteristics of oil contaminated with particulates using PIV

PurposeThe paper aims to clarify the influence of the equivalent particles number (EPN) change on the flow velocity characteristic.Design/methodology/approachThe paper opted for an exploratory study using PIV technology to obtain the transient flow toxicity vector of oil in the square pipeline.FindingsThe paper provides empirical insights about the influence of EPN on the flow average velocity which is most prominent in the middle of the pipeline, and smaller EPN values have a greater impact.Originality/valueThese influence laws of EPN can be used to obtain the dynamic characteristics of oil, which provides theoretical support for oil pollution control and effective treatment measures and lays a preliminary foundation for the online monitoring of particles in oil.
