Development of Predictive Model for Sizes of Gas and Liquid Slugs Formed in Millimeter-Scale T-Shaped Channels |
| 초록 |
Gas-liquid slug flow in micro/millimeter-scale channels is attractive in a broad range of applications because of its high mass and heat transfer rates. In almost all applications, the sizes of slugs need to be known precisely, since the mass transfer characteristic depends on the slug length. To estimate the slug length from design and operating conditions, a number of models have been developed so far for micro-scale T-shaped channels. To reduce the experimental efforts, the physically sound model has been developed but are limited to micro-scale T-shaped channels. In this study, the applicability of the existing physically sound model is experimentally investigated in the case of millimeter-scale T-shaped channels under various conditions. As a result, it can be seen that the slug generation mechanism is significantly different from the existing research results under specific geometric conditions. Taking these results, the combination of physical and empirical models is newly developed. |
