PETA POLA ALIRAN DAN FRAKSI HAMPA ALIRAN DUA FASE AIR-UDARA PADA KEMIRINGAN PIPA PLEXIGLASS 45° KE ATAS

Two-phase flow is a simultaneous flow of several types of phases that interact with each other in a channel, forming specific flow patterns. Pipe inclination significantly influences flow pattern distribution and transition boundaries between flow patterns. Two-phase flow pattern maps cannot be generalized for all pipe sizes and inclination angles. This study investigates the characteristics of air-water two-phase flow in a 0.0254 m diameter plexiglass pipe inclined at 45° upward from the horizontal side. The research was conducted using an experimental method with water flow rate variations of 0.00028-0.00047 m³/s and air flow rate variations of 0.00020-0.00040 m³/s, resulting in 49 test conditions. Visualization was performed using a Canon EOS 750D camera at 60 fps for video and 5 fps for photos over a 1 meter observation area. The research identified two main flow patterns, bubble flow pattern and slug flow pattern. Bubble flow pattern occurred at water superficial velocities of 0.7468-0.9334 m/s and air superficial velocities of 0.3945-0.4603 m/s with void fractions of 0.3633-0.3949. Slug flow pattern formed within the range of water superficial velocities of 0.5601-0.9334 m/s and air superficial velocities of 0.3945-0.7891 m/s with void fractions of 0.4079-0.5504. Analysis shows that void fraction increases with increasing air superficial velocity, while increasing water superficial velocity decreases the void fraction value. The flow pattern map generated shows differences from previous studies due to the effect of pipe diameter.
