Summary: | [Display omitted]
•Boiling at a hot wire is considered.•Temporal fluctuations of wire temperature are recorded.•Fourier transform is applied to experimental log.•Forthcoming boiling regime predicted.
Determination of forthcoming boiling regime is one of the challenging problems in diagnostics of industrial systems where rapid thermal transients exist. Taking into account intensive temperature oscillations met there, a conventional, boiling-curve based forecast becomes inaccurate. In the present paper we demonstrate the technique to cope temperature instabilities and predict the regime employing them. The method is validated against two experimental datasets, considering liquid nitrogen at 1–4 bars and water at normal conditions. |
