The aim of the study was the implementation of a numerical simulation of the air-water two-phase flow in the minichannel and comparing results obtained with the values obtained experimentally. To perform the numerical simulations commercial software ANSYS FLUENT 12 was used. The first step of the study was to reproduce the actual research installation as a three-dimensional model with appropriate and possible simplifications -future computational domain. The next step was discretisation of the computational domain and determination of the types of boundary conditions. ANSYS FLUENT 12 has three built-in basic models with which a two-phase flow can be described. However, in this work Volume-of-Fluid (VOF) model was selected as it meets the established requirements of research. Preliminary calculations were performed for a simplified geometry. The calculations were later verified whether or not the simplifications of geometry were chosen correctly and if they affected the calculation. The next stage was validation of the chosen model. After positive verification, a series of calculations was performed, in which the boundary conditions were the same as the starting conditions in laboratory experiments. A satisfactory description of the experimental data accuracy was attained.

“…In the present experiment, the values of C 0 are 1.68 and 178, respectively. The value of C 0 for 3 mm x 3 mm channel is bigger than 3 mm x 6 mm channel because it had the increasing hydraulic diameter, D. Sowenski [6] and Ide [4] resulted that the values C 0 are 1.27 and 1.2, respectively. …”

“…The measurement of bubble size, bubble velocity, and specific interfacial area in two-phase flow of air and water has always been a challenging problem. Bubble velocity measurement is used to determine the value of C 0 and u G in the bubble nose velocity equation that proposed Ide and Fukano [4].…”

ABSTRACT: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 experimentally determined. 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 based on the digital image analysis was applied. The value of gas phase velocity was defined by the values of distribution parameter C 0 . The relation describing the value of gas void fraction depended on the Bankoff coefficient and gas input volume fraction.
