Abstract

Viscous and incompressible flow is simulated over an equilateral triangular obstacle placed in a horizontal channel. Different from the previous studies, the governing Navier-Stokes equations along with appropriate boundary conditions are solved by a particular finite volume generated code. A fixed blockage ratio (β=0.05) is considered. Different ranges of Reynolds numbers in laminar regime under critical value of the Reynolds number (Re ≤ 38.03) are investigated. Range of this study is from 1.4 to 38.03. The flow characteristics are analyzed in the forms of streamlines and pressure fields at various Reynolds numbers. Diagram of drag coefficient versus Reynolds numbers is presented and discussed. Results are compared with the available data in the literature that display good agreements.
