In this paper, a numerical study on stagnation pressure drop characteristics in configurations of sudden expansion with central restriction only (Model-1) and sudden expansion with central restriction and fence (Model-2) has been carried out. The two dimensional steady differential equations for conservation of mass and momentum are solved for Reynolds number ranging from 50 to 200, percentage of central restriction (CR) from 10% to 40% and for an aspect ratio (AR) from 1.5 to 6 for both the sudden expansion configurations. The effect of each variable on average stagnation pressure drop at the location of maximum average static pressure rise has been studied in detail. From the result it is noted that average stagnation pressure drop at the location of maximum average static pressure rise is less at lower aspect ratio, lower percentage of central restriction and higher flow Reynolds number. When two models are compared this pressure drop is always less for Model-2 when all other conditions remain same.
