Abstract: The acoustic method is an effective method for multiphase flow measurement. Wherein, reliable
sound speed model underlines the acoustic method that is based on the sound flight time sheme. This paper
systematically sorts out the gas-solid two-phase sound speed models established by different scholars, from dif-
ferent theoretical bearings. In order to intuitively present the difference, development, and defects, quantitative
simulation and experimental measurements was performed for comparison and characterization between the
sorted four different models. Relative to the coupled sound speed model, the scattering-based model, and the
developed pseudo-homogenity model that considers acoustic characteristics, the traditional pseudo-homogenity
sound speed model is remarkably smaller in terms of changing particle concentration in the gas-solid two phase
flow. The reason was drawn that the latter does not consider the influence of the relative movement between
the two phases in flow. By comparison, the other models considering the interaction between different phases
give close sound speed values relative to the experimental measurements, with certain small drops.
