Calculation Diffusion Coefficient of Drying Clay Ceramics Using Firefly Algorithm With Study the Effects of Part Geometry

Authors

Abstract

In this study, the effects of temperature, relative humidity and air velocity on the effective coefficient diffusion on four different sample clay ceramics were investigated. A full factorial design of experiments on four cubic samples was performed. In each trial mass and volume reduction were measured using an electronic balance and a vision system and the resulting data were recorded and the drying curve was plotted. Effective diffusion coefficient of moisture using drying curves were calculated using of newly developed Firefly algorithm in which the error defined as the difference between the analytically values and the experimental values were minimized. Statistical analysis and analysis of variance showed that in calculation of the effective diffusion coefficient; the velocity, the temperature and the humidity are independent of each other. The greatest impact on the effective diffusion coefficient is related to the velocity, Followed by temperature and environmental humidity respectively. Finally from the drying parameters the regression of the diffusion coefficient was obtained.
