On the simulation test of the comressor 1, in the meanwhile, the operation of the process 5 is stopped, the valves 4 and 6 are closed, and the valve 9 is opened. The compressor can be set in the same load condition as the process 5 and therefore in test operation.OOIZUMI JIYUNICHI...
The compressor assembly is made up of a prime mover and a centrifugal compressor. McQuay Distinction™series chillers use liquid refrigerant cooled hermetic electric motors (an industry first). The centrifugal compressor is a non-positive displacement type. It raises the pressure and temperature of ...

The results of a series of numerical simulations for the NASA low-speed centrifugal compressor are presented. Large-eddy simulation (LES) is carried out together with the most commonly used Reynolds-averaged Navier-Stokes (RANS) models, including the mixing length, k - and k - models. Predictio...
SimulationEngineering simulationSurgesA testing campaign performed on a centrifugal compressor test-loop showed that multiple areas of stable operation existed that were not expected. It was shown during the tests that after a first region of instability at low flow rates, a second stable region ...
In order to reduce the development time and costs of the compressor surge control system,a centrifugal compressor surge simulation model was established based on dSPACE real-time simulation platform and Matlab / Simulink modeling methods.Hardware-in-the-loop simulation platform was built for surge acti...

A simulation of three-dimensional thermo mechanical behavior of a centrifugal compressor blade is carried out by means of calculation codes based on the finite element method ”Abaqus”. The research works that had been undertaken and which have a direct or indirect relation and impact on the ...
Simulation results with three grid plans. For adiabatic efficiency of impeller, 1D code can present the results with and without parasitic losses. However, CFD does not usually include parasitic losses unless the exact practical structure of centrifugal compressor is built. That is the reason why Fi...
