The flow around a rotating cylinder is of primary importance to many chemical engineering application fields. The purpose of this work is to investigate the isothermal sublimation of a rotating vertical cylinder of naphthalene immersed in a cylindrical container where a small stream of nitrogen was uniformly blowing gently. The study is developed on both experimental and theoretical aspects. A number of mass transfer experiments and simulations have been planned and performed, in order to obtain engineering estimates in terms of amount of naphthalene sublimated per unit time at various operating conditions such as surface temperature, inert flow rate and the rate of rotation. The experimental values have been compared with the simulated results. Both, 2D axisymmetric and 3D, stationary models based on transport phenomena in dilute solutions and incompressible fluid flow have been adopted.

Abstract
The flow around a rotating cylinder is of primary importance to many chemical engineering application fields. The purpose of this work is to investigate the isothermal sublimation of a rotating vertical cylinder of naphthalene immersed in a cylindrical container where a small stream of nitrogen was uniformly blowing gently. The study is developed on both experimental and theoretical aspects. A number of mass transfer experiments and simulations have been planned and performed, in order to obtain engineering estimates in terms of amount of naphthalene sublimated per unit time at various operating conditions such as surface temperature, inert flow rate and the rate of rotation. The experimental values have been compared with the simulated results. Both, 2D axisymmetric and 3D, stationary models based on transport phenomena in dilute solutions and incompressible fluid flow have been adopted.Pubblicazioni consigliate
