Abstract: | Testing centrifugal fan flow field by physical laboratory is difficult because the testing system is complex and the workload
is heavy, and the results observed by naked-eye deviates far from the actual value. To address this problem, the computational
fluid dynamics software FLUENT was applied to establish three-dimensional model of the centrifugal fan. The numeral model
was verified by comparing simulation data to experimental data. The pressure centrifugal fan and the speed changes in distribution
in centrifugal fan was simulated by computational fluid dynamics software FLUENT. The simulation results show that the gas
flow velocity in the impeller increases with impeller radius increase. Static pressure gradually increases when gas from the
fan access is imported through fan impeller leaving fans. |
