Adjoint-based Shape Optimization for the Minimization of Flow-induced Hemolysis in Biomedical Applications

no code implementations26 Jan 2021 Georgios Bletsos, Niklas Kühl, Thomas Rung

An optimized shape, leading to a potential improvement in hemolysis induction up to 22%, is identified.

Adjoint Complement to the Universal Momentum Law of the Wall

no code implementations17 Dec 2020 Niklas Kühl, Peter M. Müller, Thomas Rung

As a direct consequence of the frequently employed assumption that all primal flow properties algebraically scale with the friction velocity, it is demonstrated that a simple algebraic expression provides a consistent closure of the adjoint momentum equation in the logarithmic layer.
