INVESTIGATION OF FLOW FIELD OVER POST FLOW MODEL WITH THE AID OF ePIV SYSTEM

Abstract

Post flow model was used in the present study as an insert model for the interactive
flow study innovative device namely called ePIV. The separation of the flow and its
subsequent reattachment to a solid surface occurs in many systems, and is of practical as
well as of theoretical interest. Three different values for the upstream velocity were selected
in the present work within the range (14, 24, and 32 mm\s) and two set of figures were
observed for every value of upstream velocity. First set for velocity vector plots and shaded
color plot while the second is for picture frames captured for the purpose of ePIV system
software. It was found that ePIV system can be used in diverse educational settings because
of its effectiveness as an educational tool, high-tech appeal, compact size, low cost and
safety. Also, It was concluded that the sudden appearance for the post height result in a
vortex spot that lead to an adverse pressure gradient concentrate the majority of high bulk
velocity magnitude at the upper half of the post flow model height.
