Abstract

In this paper 2D flow field and free surface analysis around semicircular and circular obstructions in a duct is numerically studied. The governing equations are numerically solved in the domain by the control volume approach based on the SIMPLE technique. Validation of present simulation was performed with several test cases and comparisons show the good agreement with the literature. Final profile of free surface in the vicinity of obstruction is comprised with the profile in a duct without any obstructions. Present results show, as the obstacle size grows, the level of the free surface at the upstream grows and the height of the free surface at the downstream decreases.
