Method of managing the phenomenon of technical field of a chemical species in the context of a system of the study by simulation of a physical configuration

摘要

The system includes a first level (N1) of modular elements, a second level (N2) of coupling modules, a third level (N3) for assembling data transmission paths, a fourth level (N4) of study generators, a fifth level (N5) as man-machine interface. The system includes components which act in the following stages. A first component resolves the transport equation of the soluble sample. A second component performs a test on the results curve in which the behaviour of the solution in concentration is observed. A third component manage the saturation in which a new transport equation is formed for the first stage by replacing the limit condition of the material flow as input by a concentration limit condition as input. A fourth component depletes the precipitate in which the result of the third stage problem is a curve of the concentration as a function of time for all x. For x = 0, there is an instant (Tep) where this curve passes below Csat. This instant of depletion of the precipitate, is calculated from the solution, and determines the instant where the regime passes from saturation to desaturation. A fifth component manages the desaturation in which the transport problem is resolved, by replacing the material flow condition as input by another material flow condition. A sixth component obtains the solution to the problem with precipitation which is the expression of the concentration and that of the flow for all x and all t, for the fifth stage solution.
