Abstract

Pressure drop is one of the most important parameters used to characterize two-phase flows. It is the key physical value for determining discharge in the downcomer, with the help of experimental pressure drop,it is useful for finding other two phase flow properties such as void fraction ,gas velocity experimental results are required for the validation of theoretical models. This analysis helps for the modelling /design of two phase device The experimental facility consists of an adiabatic air lift loop associated with multiple risers with necessary instrumentation consists of a data acquisition system, ultrasonic flow meter for the measurement of water flow rate, rotameter for the measurement of airflow rate and pressure transducers for the measurement of pressure drop .An internal Air-Lift Loop (ALL) with two risers, two Spurger’s and one downcomer is designed and constructed for the study of its pressure drops.. Ultrasonic flow meter is located in the downcomer to measure the liquid flow rate. The present work is carried out to determine differential pressure drop in single risers and multiple risers for different air flow rates and different levels of water in the separator tank .Differential Pressure drop is determined experimentally by using two phase piezo electric differential pressure transducer connected across pressure tapings with 1mt distance is used. The distance from top most pressure taping in the riser from the separator is 1.56 m
