Racca, A. : "Turbocharger Design and Optimization by Adjoint Method Coupled with CHT Analysis", In “Review of the VKI Doctoral Research 2018-2019”

This paper addresses the problem of multidisciplinary adjoint optimization methods for turbocharger Variable Geometry Turbine components with focus on thermal aspects. A Conjugate Heat Transfer procedure based on a loose coupling between a fluid and solid solver is introduced as a means to predict the heat transfer and temperature in the rotor. Consequently, as this method will be used to optimize the rotor in a gradient based framework, the adjoint method to the loose coupling procedure is presented to allow for an ecient computation of the objective function gradient.
