摘要
讨论了相似通风机流道中流体流动摩擦损失计算公式。推出了不同的流道表面相对粗糙度情况下模型与实物流动效率之间的计算公式。
The calculating formula of flow frictional losses in channel of similar fan is discussed in this paper. The calculating formula for efficiency between the model under the condition of different relative roughness on surface of flow channel and the real fan is recommended.
