Time-linearized solvers are commonly used for aeroelastic stability prediction in transonic flows. Nevertheless, they often rely on a frozen turbulence assumption. This presentation goes beyond this hypothesis by detailing the differentiation of Wilcox turbulence model and its validation on a 2D nozzle featuring an oscillating shock and a separated region.
