Paper Abstract

Measurement of drop size distributions in annular two phase flow is required in many parts of industry. In the oil industry this information is needed as the drop sizes in the flow affect heat and mass transfer, pressure drops and also processes like erosion and corrosion. Laser techniques are well suited for this kind of study. In the present work, drop size distributions have been measured in a 38 mm diameter tube in vertical and horizontal positions. Phase Doppler and laser diffraction techniques have been employed for this purpose. Data has been collected for various flow conditions and has been compared with that previously obtained for 32 mm and 20 mm diameter tubes. The effect of pipe orientation on drop sizes has also been analyzed and some typical results have been produced.
