摘要:The small or mini channel is widely adopted in compact heat exchanger in particular. In present study,the values of velocity and gas void fraction in two-phase gas-liquid flow in mini-channels were experimentallydetermined. The depth and width of the rectangular cross-section of the channel were 3 mm x 3 mm and 3 mm x 6 mm.The investigated flow and channel size to be applied in measurements of velocity and gas void fraction, a method basedon the digital image analysis was applied. The value of gas phase velocity was defined by the values of distributionparameter C0. The relation describing the value of gas void fraction depended on the Bankoff coefficient and gas inputvolume fraction.
