摘要: 本文研究气液两相流在节流嘴处的流动规律，利用Fluent计算流体动力学软件，对节流嘴附近的流体流动状况进行数值模拟。分析结果表明，流体的压力、温度在节流嘴入口处急剧减小，再经过能量衰减逐渐达到平衡，总的变化趋势是减小的，为现场预防水合物的生成提供参考依据。
Abstract: In this paper, a simplified physical model at the throttle choke is established based on the Fluent Software. The flow properties of gas-liquid two-phase flow at the throttle nozzle are studied. As a result, the pressure and the temperature at the entrance of the throttle nozzle decrease sharply and then achieve a balance through the energy attenuation. The total variation trend is reduced. It provides a theoretical foundation to prevent the hydrate formation.
