Сравнительный анализ коэффициентов истечения критических сопел
Abstract
A comparative and statistical analysis of the escape rates of critical nozzles with a toroidal branch pipe is carried out. It analyzes the main approaches associated with determining the discharge coefficient. The equations of dependences obtained for describing changes of the discharge coefficients of critical nozzles as functions of the Reynolds number are given. On the example of critical Venturi nozzles, factors affecting the accuracy of measuring gas flow are considered.
