Abstract
Numerical analysis has been performed for three-dimensional developing turbulent flow in a rectangular duct containing straight cylinder placed near a bottom wall by using an algebraic Reynolds stress model. Calculated results of streamwise velocity and Reynolds stresses are compared with the experimental data in order to examine the validity of the presented numerical method and an algebraic Reynolds stress model. Comparisons with the experimental result suggest that the present method is able to predict velocity profiles correctly and reproduce the secondary flow of the second kind. Adding to this, calculated results show clearly the generation of pulsation flow near the narrow region between cylinder and bottom wall.
