Abstract EN
The presented research demonstrates the results of a series of numerical simulations of gas flow through a single-stage centrifugal compressor with a vaneless diffuser.
Numerical results were validated with experiments consisting of eight regimes with different mass flow rates.
The steady-state and unsteady simulations were done in ANSYS FLUENT 13.0 and NUMECA FINE/TURBO 8.9.1 for one-period geometry due to periodicity of the problem.
First-order discretization is insufficient due to strong dissipation effects.
Results obtained with second-order discretization agree with the experiments for the steady-state case in the region of high mass flow rates.
In the area of low mass flow rates, nonstationary effects significantly influence the flow leading stationary model to poor prediction.
Therefore, the unsteady simulations were performed in the region of low mass flow rates.
Results of calculation were compared with experimental data.
The numerical simulation method in this paper can be used to predict compressor performance.
