Abstract: In this paper, a numerical study on the performance of sudden expansion with central restriction has been carried out. The two dimensional steady differential equations for conservation of mass and momentum are solved for Reynolds number(Re) from 50 to 200 and aspect ratio(AR) from 1.5 to 6 for 0% to 40% central restriction(CR) and fully developed velocity profile at inlet. The effect of each variable on velocity profile has been studied in detail. From the study, it is observed that the region of negative axial velocity at corner zone increases with increase in percentage of central restrictions for a particular value of Reynolds number and aspect ratio. At the main flow region, velocity profiles are flattened downstream to the throat section. This flattenness increases with the increase in percentage of central restrictions. At central region, velocity profiles are also flattened but this is somewhat less compared to the main flow region. Flattenness of main flow region increases with increase in Reynolds number and aspect ratio. It is noted that the magnitude of decreased flattenness in the central region remains more or less same with increase in aspect ratio for fixed value of Reynolds number and central restriction.
Keywords: central restriction, sudden expansion, velocity profile, aspect ratio.
