Publikováno v: Volume 11: Heat Transfer and Thermal Engineering.

The objective of this work is to compare two topology optimization strategies, i.e. density-based (diffuse) and level-setbased (sharp), in thermal problems involving a heat conductor and an insulation material. The fundamental difference between the

Topology optimization for the design of additively-manufactured cooling channels

Autor: Farshad, Navah, Lamarche-Gagnon, Marc-Étienne, Ilinca, Florin, Audet, Martin, Molavi-Zarandi, Marjan, Raymond, Vincent

The design of cooling channels has a crucial impact on the efficiency of heat exchangers and other devices employed in the thermal management of industrial processes. The complexity and the multidisciplinary nature of the physics involved in these pr

A comprehensive high-order solver verification methodology for free fluid flows

Autor: Farshad Navah, Siva Nadarajah

The aim of this article is to present a comprehensive methodology for the verification of computational fluid dynamics (CFD) solvers with a special attention to aspects pertinent to discretizations with orders of accuracy (OOAs) higher than two. The
