  • Drift flow convection in partial nucleate boiling regime [Elektronski vir]
    Bašič, Sani Marko ; Škerget, Leopold
    Presented investigation treats convective effects of bubbling process in a partial nucleate boiling regime. During the ebullition cycle the bubble induces considerable flows of liquid phase in its ... vicinity over the boiling surface. To quantify these flows the partial nucleate boiling on single nucleation site has been investigated experimentally using PIV technique. It has been recognized that after inception the bubble interface passes through five different stages. Successively, these stages are hemispherical expansion, vertical elongation, base shrinking, bubble departure and rising. For each of these stages an instantaneous velocity distribution is presented qualitatively by PIV plots and also quantitatively by the velocity component distribution diagrams. By virtue of findings presented here it might be possible to estimate a convective contribution in the overall heat flux removed from the boiling surface in partial nucleate boiling regime.
