摘要：

Pulsating turbulent pipe flow was measured at the time-averaged Reynolds number of about 5. 7 multiplied by 10**4 and over wide ranges of both frequency and velocity amplitude ratio. The flow pattern in an incompressible turbulent pipe flow was found to be described by four characteristic parameters and not to be affected so much by velocity amplitude ratio. Further, the flow patterns were classified into three types, i. e. , quasi-steady, intermediate, and inertia dominant ones with respect to the dimensionless frequency omega prime . The values of omega prime are representing the limits between three regions were proposed.
