An engineering application case study on a two‐fluid flow model for the control of industrial drying operations is reported. The mathematical model of this process was numerically solved by a computer code developed in FORTRAN language and was validated through data taken from PVC drying performed in an industrial continuous fluidized‐bed dryer. The predicted steady‐state outlet temperature and PVC moisture content values agree with the real data observed on the industrial plant. This model was also used to predict the temperature and concentration profiles inside the dryer as a function of time as a response to the disturbances and variations on the PVC water content at the dryer inlet.
