This inverse problem is motivated by models that arise in food engineering. In particular, the model studied here describes high-pressure processes and it is governed by the heat equation with Robin boundary conditions in a cylindrical spatial domain. We study the inverse problem, proving a uniqueness result and obtaining a numerical scheme to compute the thermal expansion function. Several numerical examples are shown. eng restricted access On the identification of a thermal expansion coefficient journal article
