In order to further improve the efficiency and performance of the centrifugal blower,a three-dimensional model was constructed based on SolidWorks software,and numerical simulation was carried out by importing Fluent software on the basis of completing the mesh delineation and the setting of the entrance conditions,focusing on the comparison of parameters such as outlet static pressure,multivariable efficiency,full pressure efficiency and axial power for the centrifugal blowers with the shapes of trapezoidal,circular and eccentric,as well as with the conical angle of the shells of 22.5°,35° and 45°.The parameters such as outlet static pressure,multivariable efficiency,full-pressure efficiency and shaft power are compared,and the research results can guide the optimisation of the blower shell.
