Entropy generation through a porous triangle duct is investigated numerically in the present work. Developing, laminar, incompressible, and steady flow is assumed to simulate this problem. Total, friction and thermal entropy generations are calculated in terms of the pertinent parameters such as Reynolds number (Re), thermal conductivity ratio (Rc), and Darcy number (Da). All simulations are performed with commercial software Ansys-Fluent for three values of Reynolds number (Re=50, 100, and 150), Darcy number (Da=10-6, 5×10-3, and 10-2), and thermal conductivity ratio (Rc=1, 3, and 5). Results show that for a porous duct, there is 213.3% increment in the total entropy generation when the Reynolds number is increased from 50 to 100 at Da=10-2 and Rc=1. For an empty duct, there are 215.1%, 1283.5% and 339.1% increments in the total and thermal entropy generations and Bejan number, respectively when the Reynolds number is increased from 50 to 100.
