  Abstract:   This paper is a study of mass transfer in entrainer sublimation, when the solid-gas interface is plane. A mathematical model is established, that allows the calculation of the sublimation process time, or the sublimation front position as a time function. The mathematical model is experimentally checked, using naphthalene cylindrical particles, fixed on special supports, with are offering a plane surface in contact with the entrainer, here is hot air. It is also studied the influence of temperature and entrainer flowrate on sublimation rate.

Keywords: entrainer sublimation, mass transfer
