Minimum heat flux and minimum film-boiling temperature on a completely wettable surface: Effect of the Bond number

•The surface super-hydrophilicity results in increase in minimum film-boiling temperature TMFB and minimum heat flux q″min.•The increase in TMFB and q″min is strongly related to the Bond number of sphere Bos (or, diameter of sphere Ds).•The increase in TMFB and q″min can be explained by the vapor bubble releasing dynamics in film boiling.
