Note (General): This paper describes the gas-liquid interface shape and the internal flow field of a liquid bridge that is placed to bridge the cross-section of a horizontal narrow rectangular converging channel made of glass with a gap size of 1.2mm and a converging angle of 2.97°. Such a liquid bridge is moved to the smaller cross-section by surface tension. Liquid bridge are observed and transported in semi-scale channels and also in gas-liquid separator under a microgravity condition. Thus,it is important to understand the liquid bridge behavior from point of view of semi-scale flows dominated by surface tension. In the present study,a liquid bridge made of ethyl alcohol or mixture of water and ethyl alcohol as the liquid was viewed from the top and the side. (1)The internal flow fields of the liquid bridge in the side view were quantitatively measured by the brightness distribution cross-correlation method,i.e. PIV (Particle Imaging Veleimetry). (2)The gas-liquid interface shape was expressed using Fourier factors,and the feature was clarified. (3)Effects of various parameters on the liquid bridge behavior were examined.
