In this study, we analyzed the effect of perforated plates in rectangular tube with sudden enlargement as some local perforated plates in each region. The overall length of rectangular tube is 1.4m and the experimental data for validating numerical simulation is based on the previous work performed by the authors in this study. The flow regimes, 18,700, were selected, and area ratio between plate and holes in the perforated plate is 1:1 at all cases. The numerical analysis was carried out by using the Large-Eddy Simulation to study the instantaneous flow characteristics. The results obtained useful guidelines for securing uniformity and suppressing pressure drop when applying the perforated plate.
