Abstract: | The forms of bubbly flow occurring within a tube bundle are discussed and the boiling process in the bundle is notionally divided into mechanisms due to liquid forced convection, sliding bubbles and nucleation. A novel experimental analysis of heat transfer from a tube in a bundle indicates the predominance of the sliding bubble part. There is a virtual absence of nucleation in a bundle except at the lowest tubes indicating that, once enough bubbles have been produced, the other mechanisms are sufficient to transfer the heat from the tubes. |
