Applications of (Mpdx) method in the numerical simulation of distributed and lumped parameter processes, for isotopic separation columns

The paper proposes a solution for the numerical simulation of the 15N isotope distributed parameter separation process. In order to simulate the separation process, the matrix of partial derivatives of the state vector method, associated with Taylor series, is used. Also, an alternative form of a partial differential equation, of second order with two independent variables, is proposed to the Cohen equation, as the process model. The approximating solution which verifies the proposed partial differential equation represents an original element, too.
