Abstracts : In this paper, on an experimental facility the
signal characteristics of DN50 trapezoidal dual bluff
body vortex flow meter are investigated with steady
flow. The results are presented for the nine dual
trapezoidal bluff body combinations with opening
length varying from 40.5mm to 115.5mm with
blockage ratio of 0.26, 0.29 and 0.31. For each
blockage ratio the influence of three after shape angle
(16°, 19° and 22°) are investigated. The vortex
frequency is calculated by using zero crossing method.
The Linearity of Strouhal’s number is used as
parameter for comparison. The results show that the
vortex frequency increases for the 0.26 and 0.29
blockage ratio by using dual bluff body. For the 0.31
blockage ratio, the vortex frequencies is almost same
or less for all after shape angles and opening lengths
than the reference single bluff body. The best linearity
of Strouhal’s number was observed for 22° after shape
angle combinations for all blockage ratios.
