Characteristics of Pressure Fluctuation in Entrance Region

open access: yesJAPANESE JOURNAL OF MULTIPHASE FLOW, 1988
This paper presents the characteristics of the pressure fluctuation in the entrance region in solid-liquid flow. To investigate an axial developing process of the pressure fluctuation, six pressure transducers were set at intervals of 2m in the test pipe.It was found from the experiment that in the range of higher velocities, the maximum pressure ...
