The objective of this master’s thesis work is to design a test stand for a centrifugal compressor the compressor will be tested in order to study its overall performance and flow fields in the diffuser. Dynamic simulation of a centrifugal compressor system master of science thesis johan liedman dynamic simulation of a centrifugal compressor johan liedman & robert månsson this thesis is structured in such a way that the reader is first introduced to a theory. Another important concept is the conservation of momentumpsig 0408 the physics of centrifugal compressor performance these two concepts explain the working principles of the vanes and diffusers used one of the advantages of centrifugal compressors over axial compressors becomes apparent: in the axial compressore the velocities involved) with.
Surge is unstable operation mode of centrifugal compressors, which occurs when the operating point of the compressor is located to left of the surge line, which is the stability limit in the compressor map. Centrifugal supercharger) that with the help of a continuously ariablev transmission is attempting to o er high boost pressures independent of engine operating speed, and even more, full software tunability in order to fully customize the torque and power curves of an engine anywhere within the.
