EXPERIMENTAL INVESTIGATION OF PRESSURE DROP OF COUNTER CURRENT AIR-WATER FLOW IN A VERTICAL COLUMN

چکیده مقاله

In this present work, the experimental pressure drop in a counter current air-water flow in a vertical column has been measured. For this reason, an experimental work is done in a vertical bubble column with 0.1 m diameter and 3 m height. The experimental study is carried out in upward flow of air and a downward flow of water at ambient temperature. The air and water superficial velocities are in ranges of 0.4 to 2.12 cm/s and 0.64 cm/s to 2.72 cm/s, respectively. The experimental data of pressure drop is obtained and discussed. This study is clarified the effect of different flow regimes due to variation of gas and liquid superficial velocity on the pressure drop in bubble column.
