AB  - This article deals with the contribution of reduced models in the context of estimating the thermal diffusivity of liquid metals. The identification of this property is carried out using an experimental setup suitable for high temperatures, combined with an inverse process involving a numerical model that describes the transient thermal conduction and advection phenomena within the molten metal. A modal reduction technique of the numerical model is proposed here, in which temperature and velocity are decomposed on a POD basis. This double reduction procedure allows for a significant reduction in the order of the numerical model used in the inverse procedure, and thus in the identification computational time compared to classical finite element models. Initial results demonstrate the benefits of the technique in terms of results accuracy and computational speed.
