As partner of the FP7-AAT project RBF4AERO, the RBF Morph team will take part in the 11th edition of the International Conference on Evolutionary and Deterministic Methods for Design, Optimization and Control with Applications to Industrial and Societal Problems, EUROGEN 2015, the will be held in Glasgow (UK), 14-16 September, 2015.
A work concerning the reduction of the drag of an automobile model using an optimzation based on an adjoint-morphing coupling will be presented.
Abstract “Aerodynamic Optimization of Car Shapes using the Continuous Adjoint Method and an RBF Morpher”
This paper presents the application of the continuous adjoint method, programmed in OpenFOAM, combined with an RBF-based morpher to the aerodynamic optimization of a generic car model.
The continuous adjoint method produces accurate sensitivities by utilizing the full differentiation of the Spalart-Allmaras turbulence model, based on wall functions, while the RBF-based morpher provides a fast and versatile way to deform both the surface of the car and the interior mesh nodes.
The integrated software is used to minimize the drag force exerted on the surface of the DrivAer car model.
