THREE-DIMENSIONAL RECONSTRUCTION OF GAS-LIQUID TWO-PHASE FREE SURFACE FLOWS
The study of gas-liquid two-phase free surface flow is of great significance in both natural phenomena and engineering applications.This paper focuses on the application of binocular vision technology for three-dimensional reconstruction and measurement of gas-liquid two-phase surfaces.The hardware configuration,operation process,image post-processing algorithms,and key considerations of the binocular vision system are described in detail.The effectiveness of the system is verified through three specific experimental cases:solitary wave running-up and breaking,wave breaking induced by structures,and ventilated cavity around an axisymmetric slender body.The results show that the binocular vision technology can achieve high-precision three-dimensional reconstruction of gas-liquid interfaces at the laboratory scale,effectively capturing complex interface configuration.This provides reliable measuring approach for experiments in gas-liquid two-phase free surface flows.
