Abstract

This research presents the numerical results of the influence of aspect ratio and laminar Reynolds number in the behavior of the flow in a rectangular duct with step (FFS). Three different Reynolds (300, 400, and 500) and 3 different ratios of contraction (8, 4, and 2.7) are analyzed. The numerical study is performed with the developed program called FLUSS, the code is based on the technique of finite volume and SIMPLE algorithm, validation of the numerical code is compared with the experimental results obtained with the laser technique of particle image velocimetry. Numerical and experimental results present a maximum difference of 4%.
