Abstract:

Nonlinear heat and mass transfer equations are modeled by means of electric simulation. The difference equations are simulated by the relationships on the networks obtained from Kirchhoffs law. The article discusses an electrical model for the solution of the system of differential equations in 2 unknown functions with a moving intensive evaporation surface. The heat and mass transfer equations are simulated by 2 resistance circuits. Each half of the circuit presents an independent boundary problem. Electrical modeling showed satisfactory agreement between the function which was obtained and the full scale experiment.
