Abstract
The study of drag and lift forces on natural or manmade physical objects in confined domains owns both practical and theoretical importance in the field of general sciences, which particularly includes physical science. In this regard, this work is the numerical effort to examine drag and lift coefficients for the moving liquid stream at a low Reynolds number in the Convergent-Divergent (CD) channel. The liquid stream flows with the parabolic profile from the inlet and interacts with the case-wise infinite cylinders as barriers in the right vicinity of CD throat. The differential formulation is designed toward CD channel for the flow area, and the numerical solution is stated using the hybrid meshed finite element method. The contour and line graph analysis was conducted for a greater understanding of the involved flow variables. The comparative analysis is enclosed by setting a fixed Reynolds number for the hydrodynamic forces against mounted obstacles in a CD throat. It is seen that the square-shaped cylinder experienced the greater drag force as compared to the circular obstruction.& nbsp;(c) 2022 Author(s).
