WebBoiling heat transfer is characterized with an S-shaped curve relating heat flux to the temperature difference between the fluid and the heated surface [1], see Fig. 1. This curve, first obtained by Nukiyama [2] is called the boiling or Nukiyama curve. There are two ways to cover the boiling curve, controlling temperature or controlling power. WebBoiling is a common occurrence in our daily lives, e.g., the pool boiling of water in a pan, or flow boiling in an espresso machine. Boiling heat transfer is generally described by a pool boiling curve, as shown in Fig. 1, which was first reported by Nukiyama [16].
