Nozzle-flapper sensor mechanistic and statistical concurrent modeling

Novel technique has been fashioned for mechanistic and statistical concurrent modeling. This methodology combines the traditional approach in elaboration of mechanistic model and, for attainment adequacy and required precision employs a statistical edition by the data based modeling of discrepancy between theoretical and experimental data. The basic concepts and analysis of the mechanistic and statistical concurrent modeling and its application to nozzle-flapper sensor model building and solving for back-pressure focus system were described. From mechanistic-statistical concurrent model validation it was found that this approach in comparison with pure data based modeling permits attains less discrepancy to experimental evidence.
