Coupling Analysis of Low-Speed Multiphase Flow and High-Frequency Electromagnetic Field in a Complex Pipeline Structure

Figure 1

A water holdup measurement device with a terminal short-circuit dual coaxial transmission line. 𝑃₀ is port 0, and 𝑃₁ is port 1. A is the upper cavity filled with air as medium 0. 𝐹 is the lower filled with mixed fluid as medium 1. 𝐶₁ and 𝐶₂ are conductors 1 and 2. The arrows indicate fluid flow inlet and outlet.
