PENGURANGAN INTENSITAS FLUKTUASI TEKANAN PADA PEMBESARAN MENDADAK ALIRAN UDARA – AIR SEARAH HORISONTAL DENGAN PENEMPATAN RING
Abstract: This research aims
to reduce the effect of pressure fluctuations intensity on the sudden expansion
of two phase flow of air - water in the same direction with the horizontal
placement of the ring. Measurements done by installing a differential pressure
transducer device that is placed on pressure points before and after sudden
expansion. Output voltage signal recorded by a digital storage osciloscope.
Tests conducted on water discharge 0.000038 m 3 / s; 0.000078 m 3 / s; 0.000116
m 3 / s; 0.000154 m 3 / s; 0.000198 m 3 / s; 0.000244 m 3 / s; 0.000284 m 3 / s
and air flow 0.000065 m 3 / s; 0.00013 m 3 / s; 0.000195 m 3 / s; 0.000255 m 3
/ s; 0.00032 m 3 / s; 0.000385 m 3 / s; 0.00045 m 3 / s. Results showed that if
the total mass flow rate increases the pressure drop increases. Installation of
the ring can reduce the pressure fluctuations intensity, the most effective
installation of the ring using the ring the same diameter. Flow path is
generally slug and plug flow pattern.
