Some recent examples of passive techniques are treated surfaces, extended surfaces, and gas additives, to name a few. For example, treated surfaces require the application of a coating. Recent work has used silicon as well as manufacturing procedures developed for microelectronics (Bergles, 2011). However, the thermal resistance of the coating must still be taken into account. Additionally, surface vibrations, fluid vibrations, and electrostatic fields illustrate active techniques. In particular, surface vibrations, at low or high frequency, are capable of improving heat transfer in a single phase (Maire et al., 2017). Higher amplitude or frequency results in an increase in the heat transfer coefficient. It is interesting to note that the best performances were recorded when the system was under resonant frequency (Maire et al..,
