Correction of procedure for conversion of gas-dynamic characteristics of high-pressure centrifugal сompressor stage in case of frequency change rotor rotation
The proposed corrected method of conversion of gas-dynamic characteristics of high-pressure stage of turbocharger operating in the area of high circumferential speeds (conditional Mach numbers > 0,5) to other rotor speeds is given in the work, taking into account deviation from kinematic and dy...

| Summary: | The proposed corrected method of conversion of gas-dynamic characteristics of high-pressure stage
of turbocharger operating in the area of high circumferential speeds (conditional Mach numbers > 0,5)
to other rotor speeds is given in the work, taking into account deviation from kinematic and dynamic
similarity conditions. The method of combined control due to creation of swirling of flow in front
of impeller and simultaneous change of rotation speed is considered. Analysis of experimental and
theoretical results is done. |
