Abstract
This paper focuses on the development of a low-speed centrifugal compressor.
In order to prepare for the numerical calculation, all parts of the compressor are designed and assembled by SolidWorks. Examine how to set initial mesh, add the boundary conditions and the convergence objective, and complete the internal flow simulation and calculate the efficiency of the compressor by COSMOSFloWorks.
There are many numerical investigations into the centrifugal compressor in this article. The influence of blade number, blade thickness, adding of splitter blades and the speed of rotation on mass flow and efficiency is showed.
