Bubble chains on a novel microstructured surface during boiling

11 Jan. 2008 | Online Presentations | Contributor(s): Alexander Ustinov

The photograph shows the boiling R134a at 7 bar and 54 kW/m2 on a novel microstructure(insert in the right corner). As it can be seen, preferable nucleation near neighboring sites leads to the formation of bubble chains pattern upon the surface. This pattern is observed in different degrees on all …
