With the continuous growth in computing power, numerical optimisation is increasingly
applied in shape optimisation using Computational Fluid Dynamics (CFD). Since CFD …

A computer-aided design (CAD) and adjoint based multipoint optimization of the LS89 high
pressure axial turbine vane is presented. The aim is to reduce the entropy generation at both …

Adjoint methods are the most e cient approach to compute the design sensitivities as the
entire gradient vector of a single objective function is obtained in a single adjoint system …

This paper presents a single point optimization of the LS89 turbine vane cascade for a
downstream isentropic Mach number of 0.9. The objective of the optimization is to minimize …

The present paper is about the turbomachinery blade geometry parameterization, which has
been developed at the DLR institute for propulsion technology for the last two decades. It …

The present thesis incorporates the CAD model into an adjoint-based optimization loop and
uses it for the shape optimization of a 2D transonic turbine blade mid-section (profile). This is …

The thesis deals with the problem of the multidisciplinary design optimization of thermally
stressed turbomachinery components, with focus on a turbocharger radial turbine impeller …
