WebNucleate boiling is a type of boiling that takes place when the surface temperature is hotter than the saturated fluid temperature by a certain amount but where the heat flux is below the critical heat flux.For water, as shown in the graph below, nucleate boiling occurs when the surface temperature is higher than the saturation temperature (T S) by between 10 and 30 … WebMay 22, 2024 · The regimes of boiling and the heat flux curve are similar (not the same) to the ones in pool boiling. The process occurs also in modern high pressure forced circulation boilers. The pioneering work on pool boiling was done in 1934 by S. Nukiyama , who used electrically heated nichrome and platinum wires immersed in liquids in his experiments.
