“…After the pioneering work of Tuckerman and Pease in 1981 [1], where the concept of microchannel heat sink was first proposed, numerous investigations have been focused on study of fluid flow and heat transfer characteristics in microchannels, as reviewed by Morini [2], Agostani et al [3] and Adham et al [4]. Generally, due to higher heat transfer coefficients of liquid coolants compared to gaseous coolants, liquid coolants are utilized with microchannel heat sinks [5].…”

The liquid flow and conjugated heat transfer performance of single-phase laminar flow in rectangular microchannels equipped with longitudinal vortex generators (LVGs) are numerically investigated. Deionized-water with temperature-dependent thermo-physical properties is employed to conduct the simulations. Three dimensional simulations are performed using an open-source flow solver based on finite volume approach and SIMPLEC algorithm. Five different configurations of the microchannel with different angles of attack of the LVGs are considered. Simulation results are compared with available experimental data and a deviation below 10% is achieved. The results show that there is a 2-25% increase in the Nusselt number for microchannels with LVGs, while the friction factor increased by 4-30%, for Reynolds number ranged from 100 to 1100. Except one at Re=100, the overall performance of the all configurations of microchannels with LVGs is higher than one. Highlights• Temperature-depended thermo-physical properties is used to improve the numerical results.• Thermo-hydraulic performance of the microchannels with LVGs is studied in details.• Higher heat transfer enhancement is observed at higher Reynolds numbers.• Microchannels with LVGs cause higher pressure loss in the device.• The overall efficiency of the microchannels with LVGs is calculated.

“…Boiling is a multi-phase and efficient thermal energy transfer process due to its high latent heat [2]. Boiling heat transfer is applied in processes where high heat flux is needed to be removed i.e., nuclear power plant [3,4], desalination [5,6], or where space is confined such as electronic cooling and thermal management of data centers [7][8][9][10], thermal management of batteries [11], heat pipes [12,13] and microfluidic systems [14][15][16][17].…”

Micro-Nano Scale Surface Coating for Nucleate Boiling Heat Transfer: A Critical Review

2018

Nucleate boiling is a phase change heat transfer process with a wide range of applications i.e., steam power plants, thermal desalination, heat pipes, domestic heating and cooling, refrigeration and air-conditioning, electronic cooling, cooling of turbo-machinery, waste heat recovery and much more. Due to its quite broad range of applications, any improvement in this area leads to significant economic, environmental and energy efficiency outcomes. This paper presents a comprehensive review and critical analysis on the recent developments in the area of micro-nano scale coating technologies, materials, and their applications for modification of surface geometry and chemistry, which play an important role in the enhancement of nucleate boiling heat transfer. In many industrial applications boiling is a surface phenomenon, which depends upon its variables such as surface area, thermal conductivity, wettability, porosity, and roughness. Compared to subtractive methods, the surface coating is more versatile in material selection, simple, quick, robust in implementation and is quite functional to apply to already installed systems. The present status of these techniques for boiling heat transfer enhancement, along with their future challenges, enhancement potentials, limitations, and their possible industrial implementation are also discussed in this paper.

“…The most interesting case is the large slip of a superhydrophobic surface, where a gas is trapped between the rough protuberances (Cassie state). Reviews on various aspects of liquid slip flow were given by Neto et al [10], Ybert et al [11], Rothstein [12], Adham et al [13], and Asadi et al [14]. In essence, the effective slip condition is given as…”
