THE CALCULATION OF A CENTRIFUGAL COMPRESSOR IN THE FLOWVISION SOFTWARE PACKAGE
Abstract
The article discusses the method of calculating the centrifugal compressor of a diesel engine in the FlowVision software package. The features of loading the model for solving the problem in the sector-sliding formulation are considered. The features of the calculation are given, such as: installation of a throttle valve with a variable angle of inclination at the outlet, limiting parameters, an adaptive computational grid. The visualization of the main parameters of the compressor in volume and in sections is presented. The test of a centrifugal compressor on a stand with different angular velocities and at different air flow rates is simulated. Based on the test results, graphs of the compressor characteristics were compiled and compared with the experimental characteristics of the prototypes TKR 700.1-01 and K27-54.3-01. The results showed good convergence, which allows us to conclude that the model was built correctly and that it can be used for similar calculations.
