Abstract
This work investigates the influence in the friction factor of a porous layer adjacent to the walls of a sinusoidal duct. The investigation is done using different properties for the porous layer, in this case, the porosity, the permeability, and the layer thickness were evaluated. This investigation is done numerically where the transport equations are applied using a control volume method. The mesh grid used is a non-orthogonal grid. For the system of algebraic equations, the SIMPLE algorithm is used to handle the pressure-velocity coupling. These simulations are made in order to obtain the pressure losses inside the duct and consequently the friction coefficient. Analysing this parameter is important to estimate the influence of the porous layer. This study found that the influence of the permeability and the layer thickness are greater than the influence of the porosity. Also, it was found that turbulent flow regimes have lower friction factors when compared to laminar flow regimes.
