Abstract
- The aim of this research is to investigate the characteristics of the sub regime of slug flow in horizontal pipe. Here, a 16 mm inner diameter horizontal pipe is utilized in order to observe the specific behavior of each flow pattern. The air and water superficial velocity are 0.7 - 8 m/s and 0.2 m/s - 1.13 m/s, respectively. To obtain thorough insight through visualization, a high speed video camera is installed on the area 190 D where the flow is fully developed. A pair of CECM sensor is also placed to gather the quantitative data from the liquid slug hold up. Furthermore, the pressure characteristics of each sub regime flow pattern are recorded by using pressure transducer. As a result, the present study has been able to provide a comprehensive data of the slug flow sub regime. Broadly, there are four observed sub regime on the slug flow. Slug and plug flow is characterized by the presence of plug flow intermittently. The less aerated slug and highly aerated slug can be distinguished by the degree of aeration which can be verified by liquid hold up measurement. While the slug and wavy flow contains wavy interface on the stratified layer. The analysis of each flow pattern is followed by the propose of a slug flow sub regime flow pattern map which can be a reference for conducting further study or fulfilling industrial need [ABSTRACT FROM AUTHOR]
