Simulation of operation of a flow sensor of variable pressure differential

In operation the results of study of influencing of uniform depositions and residual deformations of a diaphragm are introduced flow sensor of variable pressure differential on magnitude of coefficient of the expiration. The results are obtained by a numerical modeling of operation of the sensor by finite element method with usage of the program Ansys. The move of air in the channel of a constant cross-section was modeled. Statistical treating and analysis of the obtained results are fulfilled by facilities of the program Statistica Enterprise. The quantitative estimation of influencing of each of the indicated factors on magnitude of coefficient of the expiration is given.
