| Tartalmi kivonat: | The heat and mass transfer was studied in case of porous material. The models were spheres which were made in different sizes from gypsum and the mixtures of gypsum and paper. The weight loss, the water content and the temperature of the product were tested on different air velocities during each experiment. The physical properties of the samples were measured in the interest of determination of heat transfer data. The calculated heat transfer coefficients on the basis of measured data have shown a difference from the results of heat transfer data - including dimensionless equations - derived from literature. The mass transfer was studied during the steady-state period and the results confirm the tendency the dimensionless Sh equations suggested in the literature. |
