气液两相节流数值模拟
Numerical Simulation of Gas-Liquid Two-Phase Flow in Throttling Process
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.
