| 1/3 | 1800 | 480 | 40 |
| 1/2 | 1800 | 588 | 41.5 |
| 5/8 | 1800 | 625 | 42.8 |
| 3/4 | 1800 | 660 | 44.5 |
| 1 | 1800 | 706 | 51 |
From the simulation structure, when d1/d2 is 5/8, the air volume does not reach the maximum value, but the noise is in an acceptable range, when d1/d2 is increased to 3/4, the noise is increased although the air volume is increased, when d1/d2 is increased to 1/1, the air volume and the noise are increased, but the noise exceeds the acceptable range; when d1/d2 is reduced to 1/2, although the noise is reduced, the air volume is reduced; when d1/d2 continued to decrease to 1/3, the air volume had reached an unacceptable level; as can be seen from the above table, when the ratio of d1/d2 is between 1/2 and 1, the air quantity and the noise are both within the acceptable range and the difference is not large, and when the ratio of d1/d2 is less than 1/2, the air quantity is reduced quickly, and the effect is not good; when the ratio of d1/d2 is greater than 1, the noise contribution is greater. That is, only when d1/d2 is in the range of 1/2 to 3/4, the air volume and noise are within acceptable levels.
