SCIENTIFICALLY-GROUNDED RE-QUIREMENTS FOR COMPARATIVE PARALLEL TESTS OF CENTRIFUGAL DUSTER COLLECTORS

Abstract

The article provides the consistency check and accuracy evaluation of measurement of aerodynamic parameters of centrifugal dust collectors. It analyzes the requirements of normative-technical documentation to schemes and methods for conducting aerodynamic tests and then selects the most optimal one. The paper presents errors calculations of pressure, velocity and airflow measurements by the combined pressure inlet in combination with a differential manometer. It also verifies the accuracy of the experimental determination of the unknown parameters on the example of the total pressure. To improve the accuracy of measurement it is recommended to use different pressure probes, taking into account the measurement ranges.
