摘要：

Measurements of velocities and pressure gradients in pulsating turbulent pipe flow are performed by means of a directionully sensitive Laser-Doppier Velocimeter and inductive pressure transducers. The desired accuracy of the instrumentation was confirmed by preliminary tests in turbulent pipe flow without pulsations and in laminar oscillating flow. The temporal and spatial velocity field in the pulsating turbulent pipe flow could be satisfactorily determined for the entire flow field with the exception of the region extremely close to the wall (y < 0.0065, where y expresses the ratio of wall distance to pipe radius). The results are discussed and compared with results of theoretical calculations. © 1979 by ASME.
