Optimal design of multi-blade centrifugal fan based on partial coherence analysis
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021Considering that there are many design variables in multi-blade centrifugal fans, the complicated design parameters and internal flow uncertainty increase the difficulty of studying fan noise mechanisms. This study adopted the impact noise between the airflow at the impeller outlet inside the fan and the volute tongue as the ...

A design method of volute profile of multi-blade centrifugal fan based on DRBF model
Physics of Fluids, 2023The forward-curved multi-blade centrifugal fan is widely used in the ventilation and household appliance industries with limited space due to its small size factor, high pressure coefficient, and large outlet flow coefficient. Conventional centrifugal fan structural designs rely on empirical data, resulting in drawbacks during usage such as low airflow

The performance analysis and optimal design of multi-blade centrifugal fan with fluent
2014 International Conference on Information Science, Electronics and Electrical Engineering, 2014In this paper, a 3d flow field of multi-blade centrifugal fan is simulated with Fluent. The influence of typical geometric parameters on fan's flow rate and noise is studied. Coupled algorithm, MUSCL discretization scheme and steady RANS equations are used to solve the internal flow field of the fan. FW-H acoustic model incorporated with the large eddy

Numerical Optimization of a Multi-blades Centrifugal Fan for High-efficiency Design
Journal of Fluid Machinery, 2004Shape of a multi-blades centrifugal fan is optimized by response surface method based on three-dimensional Navier-Stokes analysis. For numerical analysis, Reynolds-averaged Navier-Stokes equations with standard turbulence model are transformed into non-orthogonal curvilinear coordinate system, and are discretized with finite volume approximations.

Effect of Cut-off Angle on Flow Pattern of Centrifugal Multi-blade Fan
Journal of Fluid Machinery, 2010This study investigated on details of flow characteristics of a multi-blade fan for domestic ventilation. Experiments and analysis were carried out to describe on flow pattern with variations of cut-off angle near the scroll housing throat, which were performed by PIV measurement for the flow field and by total pressure probes.
