CFD-based geometrical shape optimization of a packed-bed reactor combining multi-objective and adjoint system methods

Autor: Alexis Courtais, François Lesage, Yannick Privat, Cyril Pelaingre, Abderrazak M. Latifi

This paper presents the development of a geometric shape optimization methodology based on the so-called "Hadamard boundary variation" method for performing very general domain deformations, and the related concept of domain differentiation. The resu
