The experiment result ofperformance and sound approved the fan efficiency increase and sound reduce withtype of cylinder、circular cone anti-vortex ring,it also show the numerical simulationis right,the effect of energy conservation and denoising for circular cone-type ring isbetter than cylinder-type ring.
通过对加装防涡圈前后的风机进行性能及噪声试验,证明了风机加装防涡圈后效率升高、噪声降低,也检验了数值模拟的正确性,并得出圆锥型防涡圈节能降噪的效果优于圆柱型防涡圈的结论。
