Although its efficiency is lower than that of other fans, disk fan has an obvious advantage of lower aerodynamic noise, and is suitable for air conditioning.
从圆盘风机的特点出发，分析了单个圆盘转动时，其表面带动气体的流动情况；在轴对称流动的假定下，用量纲分析法，探讨了圆盘所能带动气流层的厚度。
As compared with the practically-measured results, the analysis and the calculation theory established in this paper about cutting noise of the small-sized disk saw machine is correct.
