The boundary conditions for blowers discussed in this study consisted of inlet, outlet, and impeller wheel boundary conditions.
During the unsteady calculation, oscillating values of pressure and velocity at several monitoring points located behind the rotating impeller wheel can be acquired.
Since the simulation is based on a rotating fluid block, the weight of the impeller wheel is not included to perform the moment calculation.
It is also concluded that the current simulation scheme does a better job for blowers with a larger impeller wheel. For the same blower, the simulation is more precise for lower rotational speed.
* The scroll shape is approximated by three circular sections whose radii are 71.2%, 83.7%, and 96.2% of the impeller wheel diameter.
* The height of the outlet is 112% the impeller wheel diameter.
The schematic of the impeller wheel and the scroll for virtual Model A+ is shown in Figure 15.
The schematic of impeller wheels with different blade angles is shown in Figure 11.
