Surrogate-based aerodynamic shape optimization of hypersonic flows considering transonic performance
Aerospace Science and Technology, 2019Aerodynamic shape optimization of a hypersonic transport aircraft over a wide Mach-number range is challenging. The difficulty is not only associated with the large computational cost of high-fidelity CFD (computational fluid dynamics) simulations but ...

Aerodynamic Shape Optimization of Heat Exchangers
2023The development of efficient methods to reject waste heat has been instrumental throughout aircraft design history. In current airliners heat exchangers cool the cabin air, avionics, and engine oil. As the aviation industry transitions toward electric or hydrogen-powered propulsion, heat exchangers will become more important.

Aerodynamic Shape Optimization by Space Mapping
2013This chapter describes an efficient aerodynamic design optimization methodology for wings in transonic flow. The approach replaces a computationally expensive high-fidelity computational fluid dynamic model (CFD) in an iterative optimization process with a corrected polynomial approximation model constructed by a cheap low-fidelity CFD model.
