WebJun 15, 2024 · Flow patterns in the channels packed with metal foams occur in different conditions from the ones recorded for empty channels so gas−liquid flow maps developed for empty channels cannot be used to predict analyzed flows. A new gas−liquid flow pattern map for a channel packed with metal foams with the porosity of 0.92–0.94 was developed. WebJan 29, 2024 · The patterns are: (a) bubbly flow, (b) plug or slug flow, (c) churn flow, (d) whispy annular flow, (e) annular flow and (f) drop or spray flow. Bubbly flow (Fig. 1.4 a) has liquid as continuous phase with large number of small bubbles nearly uniformly dispersed in it. The bubbles are spherical.
