Hydrodynamic Shape Optimization of Axisymmetric Bodies Using Multi-fidelity Modeling - Simulation and Modeling Methodologies, Technologies and Application - page 213

6 Conclusions
Computationally efficient simulation-driven multi-fidelity design optimization algo-
rithm for axisymmetric hulls in incompressible fluid flow is discussed. Our algorithm
exploits a low-fidelity model, obtained through a coarse-discretization CFD simula-
tion, and a response correction method, to construct a cheap and reliable surrogate of
the fluid flow. The algorithm can be applied to both direct and inverse design ap-
proaches. We demonstrate that the optimized designs can be obtained at a low compu-
tational cost corresponding to a few high-fidelity CFD simulations.
