| Summary: | Vapor-liquid two phase flow behavior of R123 inside herringbone microfin tubes has been studied. Herringbone microfin robe is a kind of internally finned tube in which microfins are installed inside tim tube where the microfins form multi-V-shape in flow direction. For the present experiment three different types of herringbone microfin robes with helix angle β= 8°, 14° and 28° are used. Experimental observmions showed how flow diverges and converges inside herringbone microfm tube due to fin arrangement. The effect is more remarkable for larger helix angle. From the measurements of the cross-sectional liquid flow rate distribution, the liquid removal and collection and the enWained droplet are discussed. Quantity of liquid droplets is incremed with increase of helix angle. The tube with helix angle β= 28° shows higher quantity of liquid droplets than others. |
