Numerical investigation of the effect of the volute on stall flow phenomenon is presented by solving three-dimensional Reynolds-averaged compressible Navier-Stokes equations. The . Table 3 3D CFD calculations results at constant speed of 14000 rpm @ 1.6 bar back pressure. Surge is known to be a reason for the severe damage of compressing units and systems working with them. Based on the fluid components transport theory, the distribution of H2S in the flow field inside the impeller is analyzed, and discussed the influence law of pitting corrosion pits on the stress distribution and the H2S concentration of the centrifugal compressor impeller blade. The equivalent stress distribution of the impeller, which caused by the centrifugal load, the coupling effect of centrifugal load and aerodynamic load, is analyzed. Centrifugal compressors are easier to design and manufacture compared to axial compressors. 1. Jiao Sun, Jin Ding, Songying Chen, Jianfeng Li. CENTRIFUGAL COMPRESSOR 1 manual I.

Numerical Investigation on Labyrinth Seal Leakage Flow and Its Effects on Aerodynamic Performance for a Multistage Centrifugal Compressor December 2018 Journal of Fluids Engineering 141(7) loaded vaned diffuser from a pre-production turbocharger . Part II (this paper) presents numerical simulations of a low flow coefficient supercritical CO2 centrifugal compressor developed for a closed loop power cycle. Process plant optimization. 1733.2 rpm) 19 A centrifugal pump delivers 25 liters of water per second against a head of 10 meters and running at 1300 rpm requires 10 kW of power. In centrifugal compressor design, the volute plays a key role in defining the overall efficiency and operating range of the stage. The leakage flow across the shroud of a centrifugal compressor impeller has an important effect on the compressor’s performance, in particular, in the low flow coefficient compressor.
