DRUM DRYING OF FABRICS

A study of drying of textile fabrics on a drum heated by natural gas b urner is presented. In the first stage of study, the distribution of t he heat flux over the outer surface of the drum is calculated by an an alytical method. In the second stage, this heat flux is entered in a n umerical code able to simulate the heat and mass transfers in porous m edia. The simulation results validate the analytical model assumptions . Special attention is paid to the contact resistance between the drum and the fabric.
