Aiming at gas fraction measurement needs of gas-liquid two-phase flow study

a movable wire mesh sensor（ WMS） for two-phase flow measurement is designed based on principle of WMS measuring technology. The sensor has high spatial and temporal resolutions which are 3 mm and 2 500 Hz. The calibration and gas fraction algorithm are designed to calculate the instantaneous 2D local gas fraction. The plunging jet experiment verifies that the WMS is stable

and based on the original data

the average void fraction distributions of cross-section bubble entrainment phenomenon are calculated using calibration and void fraction algorithm.
