| 为研究文丘里流量计在瞬变流动流下的数学模型，利用FLUENT软件对文丘里流量计在阶跃流动下的流场进行仿真计算，获得不同阶跃流动状态下流量与差压的离散值，利用平面拟合方法获得微分方程各项系数，进而确定流量计在瞬变流动下的数学模型。 |
| 英文摘要: |
| In order to study the mathematical model of Venturi flowmeter under transient flow, the flow field of Venturi flowmeter under step flow was simulated by FLUENT software. The discrete values of flow and differential pressure under different step flow conditions were obtained. The coefficients of differential equation were obtained by plane fitting method, and then the mathematical model of Venturi flowmeter under transient flow was determined. |
