This article is contribution on the digital analysis of the RLC model of the earth connector. The RLC model of the earth connector was feigned on MATLAB. These simulations were made with the horizontal earth connector and the vertical earth connector with a ground of resistivity 1000Ω.m and on the other hand with a ground of resistivity 2000Ω.m.
The results obtained by feigning on MATLAB both electrodes show that earth connectors must be buried in depths superior or equal to 6 meters. The relevance of this article, it is to help to determine the depths to which the earth connectors of the model RLC can be buried.
Cocoa beans moisture content behavior during drying in natural convection was estimated by integration of differential semi-empiric equation and mass flow formula. The new model was found to give better result (correlation coefficient is 0.97) respectively under experimental condition (55, 70 and 105°C), solar dryer, and sun drying. In addition, knowing that the drying kinetic was inversely dependent on the temperature, we have found the high drying temperatures lead to shortening of drying phases. Finally we conclude that the exponential two-member function is the improved model to describe falling drying rate.
