摘要
文丘里管(VT)中的流体流动是一种动态流体现象,在人类生活中发挥着重要作用。有必要通过安装多个包含静态流体的开放式压力计(MoO)来进行流量安全控制。本研究的目的是了解从 1 个到 2 个 MoO 的条件下,安装 MoO 的数量对 VT 内流速特征的变化影响。研究采用了实验方法。主要研究设备包括 1 个鼓风机-恒温器系统、1 个 8 种不同直径的 VT 和 2 个含有纯水的 MoO。数据分析采用 SPSS。研究表明,在 4 Ω ≤ R ≤ 281 Ω 和 4.58 cm ≤ d ≤ 9.45 cm 的测量区间内,1-MoO 型和 2-MoO 型的风速平均值、风速对 R 的梯度(d 固定)、风速对 d 的收敛梯度(R 固定)和风速对 d 的发散梯度(R 固定)的比较分别为 1.21E+01 ms-1 vs 1.55E+01 ms-1,-2.73E-02 ms-1Ω-1 vs -4.11E-02 ms-1Ω-1,-3.13E+02 s-1 vs -4.25E+02 s-1,以及-4.31E+02 s-1 vs -4.84E+02 s-1。而其影响差异分别为不显著、不显著、显著和不显著。
Does Number Changes of Open Manometers Filled with Pure Water Impact Wind Speeds in Venturi Tube Systems?
Fluid flow in a venturi tube (VT) is a dynamic fluid phenomenon that plays an important role in human life. Flow safety control is necessary by installing several manometers of open (MoO) containing static fluid. The study's purpose was to know the change impacts of the number of installed MoOs against flow speed characters within VTs from conditions of 1 to 2 MoOs. The research uses experimental methods. The main research equipment includes 1 blower-rheostat system, 1 VT with 8 different diameters, and 2 MoOs containing pure water. Data analysis was done using SPSS. Within measurement intervals of 4 Ω ≤ R ≤ 281 Ω and 4.58 cm ≤ d ≤ 9.45 cm, the study showed the comparison of the mean of wind speed, wind speed gradient to R (d fixed), convergent wind speed gradient to d (R fixed), and divergent wind speed gradient to d (R fixed) between 1-MoO and 2-MoO type, respectively, were1. 21E+01 ms-1 vs 1.55E+01 ms-1, -2.73E-02 ms-1Ω-1 vs -4.11E-02 ms-1Ω-1, -3.13E+02 s-1 vs -4.25E+02 s-1, and -4.31E+02 s-1 vs -4.84E+02 s-1. While its impact differences are insignificant, insignificant, significant, and insignificant, respectively.
