2.2 Normal pulsation intensity distribution along the normal
direction
Fig. 3 shows the distribution curves of the normal pulsation intensity
along the normal direction when the particle size is 5 μm, 15 μm, 25 μm,
and 50 μm and the particle concentrations are 0.65 ppm, 0.97 ppm, 3.00
ppm, 6.58 ppm, and 14.40 ppm. The horizontal axes in the figures show
the ratio of the normal pulsation intensity to the oil inlet velocity
V0, and the ordinates represent the dimensionless length
of the pipeline.
