Aerodynamic shape optimization for minimum robust drag and lift reliability constraint
(2016)A methodology for shape optimization of aerodynamic bodies under uncertainties is presented. Flow-related and geometrical uncertainties are considered and quantified by probability distribution functions. The optimal shape ... -
Bayesian uncertainty quantification and propagation using adjoint techniques
(2014)This paper presents the Bayesian inference framework enhanced by analytical approximations for uncertainty quantification and propagation and parameter estimation. A Gaussian distribution is used to approximate the posterior ... -
Bayesian uncertainty quantification of turbulence models based on high-order adjoint
(2015)The uncertainties in the parameters of turbulence models employed in computational fluid dynamics simulations are quantified using the Bayesian inference framework and analytical approximations. The posterior distribution ... -
On the forward in time solution of the unsteady adjoint equations
(2014)A new algorithm for the solution of the unsteady adjoint equations is proposed in this paper aiming at overcoming the excessive computational cost and memory requirements of the conventional adjoint approach for the ... -
Structural optimization of a wing body with uncertain aerodynamic loads
(2015)An algorithm for the structural optimization of wing body structures is presented in this paper. The structural analysis for the computation of displacements and stresses within the wing body is based on a finite volume ... -
A two-step back–forth algorithm for the solution of the unsteady adjoint equations
(2016)A new algorithm for the solution of the unsteady adjoint equations is proposed in this article, aiming at overcoming the excessive computational cost and memory requirements of the conventional adjoint approach for the ...
