Abstract
Water is a liquid fluid that plays an important role in our daily lives that has properties that are easy to distribute from high pressure places to low pressure places and the opposite. The type of pump used to drain water is in the form of an airlift pump. The purpose of this study is to determine the performance of airlift pumps when operated with different variations in nozzle size and mass flow rates. In the implementation of making this airlift pump simulation, it is designed and simulated using ANSYS-based Computational Fluid Dynamic which is operated using a multiphase flow. In the simulation test with variations in the size of the nozzle diameter the greater it will cause a decrease in the discharge value of the fluid outlet and produces the shape random pressure contour. Streamlined velocity flow pattern shape obtained becomes increasingly regular with a range of velocity values which is decreasing. To determine the best performance of the airlift pump based on the variations given and to know the flow pattern phenomena that occur in the airlift pump simulation.
