Abstract
This study aimed to examine experimentally the effects of the injector on two-phase flow characteristics such as local void fraction and bubble diameter for water-air two- phase flow in a horizontal channel having 40 mm inner diameter. During the experiments, flow rate was kept constant at 3 l/s while that for air is taken as 30 and 60 l/min. Measurements were made locally via dual optical probe and the results were presented.

Summary
Multiphase flow can be considered as two-phase flow in many applications [1] It is a complex phenomenon which is explained by tough mathematical models validated by experimental studies. It is an attractive research field for the scientists to work on some of the studies performed is as follows: Several authors have measured experimentally local void fraction and bubble size for development of twophase flow models [2,3,4]. Optimization should be considered in every stage i.e. before changing cross section or through expansion [6] In such cases, development of analytical formulation is important. Experiments contribute to generate such analytical models [7]
