Reconstruction of Tesla micro-valve using topological sensitivity analysis

Autor: Abdelwahed M., Chorfi N., Malek R.

Publikováno v: Advances in Nonlinear Analysis, Vol 9, Iss 1, Pp 567-590 (2019)

In this paper, we deal with topology optimization attributed to the non stationary Navier-Stokes equations. We propose an approach where we analyze the sensitivity of a shape function relating to a perturbation of the flow domain. A numerical optimiz
