Pneumatic gauge empirical-mechanistic modelling

Back-pressure gauge steady-state empirical-mechanistic modelling has been introduced. This technique contains gauge theoretic modelling and for model performance enhancement entertains empirical-mechanistic steady-flow models of gauge flow restrictors which are formulated as the mathematical products of available theoretical and polynomial empirical approximating functions. Flow restrictor discharge coefficient variations were considered as the polynomial empirical functions of the same variables as the theoretical functions. Motivated iteration procedure was employed for minimization of model errors. The comparison of modelling results and reference experimental data has revealed that the empirical-mechanistic modelling permits to attend minimized discrepancy from empirical evidence.
