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

The full flow field model of a widely used multi-blade centrifugal fan was built, and unstructured grids were used to discrete the computational domain. The moving reference frame is adopted to transfer data between the interfaces of the rotating field and the stationary field. Pressure boundary conditions are specified to the inlet and the outlet. The

This research was inspired by the long-eared owl's ability to fly silently. For the first time in this study, a wind turbine blade is designed to mimic the wing surface and the leading edge of the long-eared owl. The commonly used two-dimensional blade profile in previous studies is replaced by a more effective three-dimensional profile.

Design Optimization of A Multi-Blade Centrifugal Fan With Variable Design Flow Rate
Transactions of the Korean Society of Mechanical Engineers B, 2004This paper presents the response surface optimization method using three-dimensional Navier-Stokes analysis to optimize the shape of a forward-curved blades centrifugal fan. For numerical analysis, Reynolds-averaged Navier-Stokes equations with k- turbulence model are discretized with finite volume approximations. In order to reduce huge computing time
