Two kinds of experimental methods of thermistor and pressure crystal were used to study the vertical gas-liquid two-phase flow with high gas content. The flow around the trapezoidal cylinder was analyzed. The results show that, High-quality vertical gas-liquid two-phase flow with high gas content is not easy to form a stable vortex street, and the thermistor-based detector is not suitable for testing vertical vortex gas-liquid two-phase flow with high gas content.
