“…In addition, some experiments have been made to enhance nucleate boiling, mainly focusing on micro-or nano-structured surfaces because of the rapid growth of surface modification and fabrication technologies. Jiang [24] investigated cylindrical shaped micro-pillar arrays with various sizes. Liang [25] showed that micropillar could decrease boiling starting superheat, and enhanced boiling heat transfer performance.…”

Pool boiling heat transfer from structured surface is simulated numerically with a 3D OTRT (optimal two relaxation time) Lattice Boltzmann method. This work shows in detail that multiple bubbles grow and coalesce over hydrophilic (θ = 50°) surfaces in 3D view, heat flux transfers from heater surface to fluid, and temperature of heater surface varies with time. Specifically, four types of geometry in microstructure surfaces are examined and compared. It is found that heat flux of S5 is the highest and its wall temperature is the lowest. When compared with S0, the heat flux of S5~S7 increased a lot due to the easier formation of vapor blanket, and cubic shaped cavity alleviates largely this deterioration. Next, the large quantity of heat from the three phase contact line in the vicinity of side wall accounts for bubble nucleation and energy from the evaporation of thin liquid between bubbles and superheated wall helps bubbles to grow further. Besides, it is found that S5 increases nucleate site density, reduces boiling incipience superheat, and enhances remarkably heat transfer performance.

“…Their results show that most of the cases coated with defective graphene have higher initial heat flux and reach equilibrium faster than the pristine graphene−coated case under the isothermal heating condition. In particular, all the graphene coatings enhance the CHF value for pool boiling by nearly two orders of magnitude.Lim and Hung (2021) demonstrated that the ultrafast transport of water molecules through the nanostructures of graphene-nanoplatelets forms an ultrathin film of water that prompts effective absorption of latent heat of vaporization Jiang et al (2021c). studied pool boiling of deionized water on the surface of cylindrical pillar arrays of different sizes and the ordinary smooth surface under atmospheric pressure.Çiftçi (2021) numerically investigated the saturated pool boiling heat transfer of two different aqueous nanofluid suspensions, namely, kaolin-distilled water and bauxite-distilled water using CFD approach and time-dependent volume-of-fluid (VOF) multiphase model to specify the vapor volume fractions and velocity vectors in both distilled water and the prepared nanofluid suspensions Hoke et al (2021).…”

This review provides a brief literature survey recorded by the Web of Science (WoS) in 2021 on the studies of heat transfer enhancement (HTE), thermal energy, process and transport intensification technologies. A topic search containing "heat transfer" or "heat transport" or "thermal transport" in the WoS resulted in over 31,360 papers published in 2021 and more than 30% were relevant to HTE, thermal energy, process and transport intensification, which indicates the importance and rapid development of these technologies and their applications.
