“…When the heating surface temperature becomes significantly hotter (above 100 °C), film boiling takes place, where a thin layer of vapor is formed that acts as insulation and results in reduced heat transfer [10,11]. Critical heat flux leads to a drastic rise in heater surface temperature [9,12,13]. It is used in various heat exchange systems and in cooling of high-energy-density electronic components [14][15][16].…”

This paper reviews the previous work carried on pool boiling heat transfer during heating of various liquids and commodities categorized as refrigerants and dielectric fluids, pure liquids, nanofluids, hydrocarbons and additive mixtures, as well as natural and synthetic colloidal solutions. Nucleate pool boiling is an efficient and effective method of boiling because high heat fluxes are possible with moderate temperature differences. It is characterized by the growth of bubbles on a heated surface. It occurs during boiling of liquids for excess temperature ranging from 5 to 30 °C in various processes related to high vaporization of liquid for specific purposes like sugarcane juice heating for jaggery making, milk heating for khoa making, steam generation, cooling of electronic equipments, refrigeration and etcetera. In this review paper, pool boiling method during heating of liquids for specific purpose is depicted. It is inferred that enhancement in pool boiling heat transfer is a challenging and complex task. Also, recent research and use of various correlations for natural convection pool boiling is reviewed.

“…Therefore, the importance of critical heat flux and the necessity of its reliable prediction need not be over exaggerated. Though the above description has been made in the context of pool boiling, the same holds good for flow boiling except for some typical situations (Katto, 1994).…”

“…Zuber (1959) and later Lienhard and Dhir (1973) postulated that the hydrodynamic instability of these jets is responsible for critical heat flux as that can disturb the replenishment of liquid to the surface. Figure 2 depicts the scenario during CHF as postulated by the hydrodynamic instability theory and considered as one of prominent mechanisms of CHF (Katto, 1994). On the other hand Haramura and Katto (1983) drew the attention of the researchers to the near wall fluid behavior.…”

A state of the art review of critical heat flux during flow boiling through mini and microchannels has been provided based on the open literature. This review mainly examines three aspects, namely the experimental investigations, the available correlations and the state of prediction using those correlations and finally the proposed physical mechanisms as well as the theoretical models. Before discussing the specific literature on microchannels, a brief overview of critical heat flux for pool and flow boiling is provided. The review has been concluded with a summary of the available information on this topic and the need for future research.
