“…Therefore, intensive studies have been done to assess the pool boiling characteristics in the past few decades [3][4]. Recently, the research interests have been concentrated on developing various heat transfer enhancement techniques, which in general produced micro-structured boiling surfaces [5][6], or altered the properties of working liquid by the addition of external agents, such as the nanofluid [7].…”

“…Recent studies have shown that the main parameters of boiling are dependent on characteristics of surface such as its structure and chemistry. [10][11][12][13][14] Therefore, for accurate prediction and control of CHF and design of surface with the maximum heat transfer, it is necessary to understand the effects of surface characteristics on the boiling heat transfer. On the other hand, studies in the field of boiling on the surfaces that are coated by nanostructure are very limited.…”

Studies on boiling show that this phenomenon is strongly influenced by geometry and chemistry of surface. One of the methods to control boiling and achieve optimum conditions for increasing the heat transfer coefficient (HTC) is to change the chemistry and structure of the surface by using coating. In this research, one of the techniques of electrochemical coating, that is called anodising, is used for coating aluminium oxide layer on the surface of aluminium samples. With pool-boiling test on anodised samples using deionised water and measuring HTC and critical heat flux (CHF), it can be concluded that porous anodic alumina coating can increase HTC and CHF of nucleate pool boiling, due to change wettability and geometrical structure of surface.

“…Two main surface characteristics influence boiling (and particularly pool boiling): micro/nano-structure addition and wettability modification. The micro/nanostructure addition has a well-known influence on boiling [9][10][11][12]. A number of studies have dealt with the enhancement of boiling heat transfer from electronic components by the use of surface microstructures [13].…”

“…Various methods have been already explored in the literature so far by treating solid surfaces in order to enhance boiling characteristics. Recently Kim et al [9] reviewed several investigations on micro/nanostructured surface design.

-The present paper reports results of pool boiling experiments on surfaces with different wettabilities. The main aim is to identify and quantify the difference in pool boiling characteristics (Onset of Nucleate Boiling-ONB, bubble detachment diameter and time) between Hydrophilic Surfaces (HPS) and Super-Hydrophobic Surfaces (SHS). A combined sample (SHS_D) with an inner SHS part and an outer HPS part is also tested, which clearly shows that the Super-Hydrophobic surface is a preferential area for the ONB, and allows to control the bubbling position. It is found that not only the ONB, but also the bubble growth and detachment characteristics are highly influenced by the wettability of the heated surface. The analysis of the experimental results reveals that SHSs require a lower wall-superheat for ONB to occur. Moreover, in SHSs higher bubble departure times as well as higher equivalent bubble detachment diameters are encountered. The vapour phase tends to stick stronger on a SHS than on a HPS, showing a tendency to create a vapour film. Furthermore, using a post processing method developed in MATLAB, the apparent contact angle at various successive time instances is extracted from the experimental snapshots for the cases of the HPS and the SHS_D. Finally, the capability of a previously verified, enhanced, CFD-based, VOF numerical model [1-3] to capture adequately the apparent triple line contact angle, from the nucleation up to the departure of an isolated bubble from the heated surface, is checked for one of the considered superheats for a HPS case.
