高流量气举阀喷嘴流动的数值研究
|
摘要
通过数值模拟的方法,用适合高速可压缩的的斯托克斯方程,模拟不同结构的气举阀喷嘴的三维高速流动,详细对比5种不同喷嘴结构在日产气15万标准立方天然气的工况状态下的压力、速度、温度等参数.研究表明:喷嘴的能量损失与特征几何参数及进出口边界条件相关,扩张管的能量损失要小于渐缩管的,并确定了5种结构中最适合该工况下的喷嘴形状和尺寸.
by means of numerical simulation, the three-dimensional high-speed flow of gaslift valve nozzles with different structures was simulated using stokes equation suitable for high speed compressibility. The pressure, speed, temperature and other parameters of five different nozzle structures under the working condition of 150,000 standard cubic natural gas per day were compared in detail.The results show that the energy loss of the nozzle is related to the characteristic geometric parameters and the boundary conditions of inlet and outlet, and the energy loss of the expansion pipe is less than that of the tapered pipe.
