Abstract EN
This paper is concerned with the numerical simulation for shape optimization of the Stokes flow around a solid body.
The shape gradient for the shape optimization problem in a viscous incompressible flow is evaluated by the velocity method.
The flow is governed by the steady-state Stokes equations coupled with a thermal model.
The structure of continuous shape gradient of the cost functional is derived by employing the differentiability of a minimax formulation involving a Lagrange functional with the function space parametrization technique.
A gradient-type algorithm is applied to the shape optimization problem.
Numerical examples show that our theory is useful for practical purpose, and the proposed algorithm is feasible and effective.
