Abstract
Several studies on the drying of ceramic materials have been developed in the various engineering and manufacturing sector. Such materials can be used for traditional applications. In many situations, it is common to use theoretical solutions such as numerical simulations that allow, with relative ease and low cost, to change the operational and geometrical conditions of the dryer or object of drying. In this sense, the results of the numerical study on the drying of ceramic bricks are presented. The brick used is a porous medium with 0.287 porosity and a permeability of 5.75x10-15m2. The conservation equations of mass, momentum, energy and matter were considered. The results of the field of pressure, velocity, temperature and volumetric fraction of the water inside the brick obtained by the commercial package Ansys CFX ®were analyzed. The results of the simulations were compared with experimental data and good agreement was observed, which allowed to analyze and discuss the results of the brick drying.
