Power-Law Fluid Flow Around A Triangular Cylinder in Laminar Flow Regime

Abstract

Fluid flow past triangular cylinder in 2D has been scrutinized numerically by solving continuity equations and momentum equations in ANSYS FLUENT (version 15), in steady laminar flow regime. The effect of the Reynolds number (10=Re=40), in case of Power-law fluid, on the local and global flow characteristics has been investigated. In addition, flow orientations showing streamlines, recirculation length and the pressure variation on the surface of the cylinder have also been observed in order to provide further physical capacity to gain an accurate and deep understanding of the detailed flow kinematics. The pressure coefficient, total drag coefficient and recirculation length, show a relatively complex dependence on the Reynolds number.
