Abstract

REFERIDO A UN METODO PARA DETERMINAR LA CONDUCTIVIDAD ELECTRICA DE UN FLUJO MASICO EN VOLUMEN BLANCO TRIDIMENSIONAL QUE INCLUYE LAS ETAPAS DE COLOCAR LOS ELECTRODOS EN UNA CONEXION DE MEDICION CON EL VOLUMEN BLANCO; ALIMENTAR VOLTAJE ALTERNO O CORRIENTE ALTERNA AL VOLUMEN BLANCO ENTRE DOS DE LOS ELECTRODOS Y MEDIR LA CORRIENTE O EL VOLTAJE ENTRE DOS DE LOS ELECTRODOS; DETERMINAR UN MODELO EN ESPACIOS DE ESTADOS QUE DEFINA LA RELACION ENTRE LA CONDUCTIVIDAD ELECTRICA, EL VOLTAJE Y LA CORRIENTE EN EL VOLUMEN BLANCO Y QUE TAMBIEN DEFINA LA EVOLUCION DE LA CONDUCTIVIDAD ELECTRICA COMO UNA FUNCION DEL TIEMPO; COMPARAR LAS CORRIENTES Y/O LOS VOLTAJES DE ACUERDO A EL MODELO EN ESPACIOS DE ESTADOS CON LAS CORRIENTES Y/O LOS VOLTAJES ALIMENTADOS Y LOS MEDIDOS; Y MODIFICAR SEGUN SEA NECESARIO, EL MODELO EN ESPACIOS DE ESTADOS PARA DISMINUIR LAS DIFERENCIAS ENTRE LOS RESULTADOS MEDIDOS Y LOS CALCUALDOS. LOS ELECTRODOS SON COLOCADOS SUSTANCIALMENTE DENTRO DE UN PLANO; Y EL MODELO EN ESPACIOS DE ESTADOS ES DETERMINADO DE MODO QUE INCLUYA EL CAMPO DE FLUJO DEPENDIENTE DEL TIEMPO DEL FLUJO MASICO DENTRO DEL VOLUMEN BLANCO
