Pengaruh perubahan geometri nosel pada aliran dua fase terhadap kinerja liquid-gas ejector

Liquid-gas ejector is an energy conversion device capable of flowing air fluid by utilizing water based on the pressure difference between two fluids without using moving parts. This study aims to determine effect changes in nozzle geometry two-phase flow performance liquid-gas ejector. The method used conducting experiment whose stages include: determining parameter, primary rate, and secondary rate. Then carry out tests installation ejectors collect data. test done alternating geometry, Next, analyze data that has been collected get efficiency or from geometry. results showed increasing tends cause a decrease coefficient nozzle. maximum produced each with 0.57; 0.64; 0.71; 0.79 0.86 respectively were 24.33%, 23.43%, 8.19%, 16.21%, 7.96%. While coefficients are 0.94, respectively; 0.81; 0.59; 071; 0.59.
