Research on noise reduction of a multi-blade centrifugal fan based on splitter blades technology

Physics of Fluids
Splitter blades were designed for the impeller of a multi-blade centrifugal fan in a range hood. The effects of different radial positions, circumferential positions of short blades, and number of splitter blade pairs on the overall noise performance of the fan were studied in detail through experimental testing methods.

Design Optimization of A Multi-Blade Centrifugal Fan with Navier-Stokes Analysis and Response Surface Method

Transactions of the Korean Society of Mechanical Engineers B, 2003
In this paper, the response surface method using three-dimensional Navier-Stokes analysis to optimize the shape of a multi-blade centrifugal fan, is described. For numerical analysis, Reynolds-averaged Navier-Stokes equations with standard k - c turbulence model are transformed into non-orthogonal curvilinear coordinate system, and are discretized with

Multi-objective optimization design of multi-blade centrifugal fan based on blade axial distortion laws

Physics of Fluids
The impeller serves as the core aerodynamic component of multi-blade centrifugal fans, playing a pivotal role in determining their overall energy efficiency. However, traditional two-dimensional planar deformation design methods exhibit significant limitations when addressing complex internal flows.
