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.

Abstract

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.
