Abstract
Purpose – The purpose of this paper is to study steady, laminar, and two-dimensional flow around and through a porous diamond cylinder. Design/methodology/approach – The governing equations are written for two zones: the clear fluid zone and the porous zone. For the porous zone, the modified Navier-Stokes equations, including Darcy, Brinkman, and Forcheimer terms are used. The governing equations are solved numerically using a finite volume approach. Findings – It was found that as the apex angle and Reynolds number decreases the wake length decreases and the separation is delayed. Originality/value – There is no published research in the literature about flow around and into porous diamond cylinders to study the effect of important parameters, such as apex angle, Darcy number, and Reynolds number.
