Advanced Heat and Mass Transfer Technologies, 2nd Edition

Topic Information

Dear Colleagues,

This Topic is a continuation of the previous successful Topic “Advanced Heat and Mass Transfer Technologies” (https://www.mdpi.com/topics/7B51IU9BQ5). Heat and mass transfer is a crucial challenge for engineers and scientists from different technical fields. Advanced heat and mass transfer technologies are critical fundamental scientific issues for important industries—such as power electronics, refrigeration and air conditioning, chemical engineering, and data centers—and can help to reduce building energy consumption, improve energy conversion efficiency, and contribute to global energy conservation and emission reduction. This Topic is open to researchers and authors who want to submit their research and review articles in the fields of electronic cooling, battery thermal management, energy storage, refrigeration, heating, ventilation, and renewable energy. We look forward to your submissions, which will be peer-reviewed by international colleagues with broad expertise in this specific topic. The topics of interest for publication include, but are not limited to, the following:

• Heat exchangers;
• Thermal energy storage;
• Fluid mechanics, heat, and mass transfer;
• Nanofluid heat transfer;
• Thermal management of electronics and chips;
• Two-phase flow and heat transfer;
• Heat transfer enhancement;
• Waste heat recovery;
• Heat pipes and vapor chambers;
• Microfluidics;
• Thermal interface materials.

The continuous change in the entrance cross-section of a parallel-plate flow channel generally affects the mass and heat transfer on the walls of the channel. In this paper, an electrochemical parallel-plate flow channel equipped with a selenoid pulse generator has been developed to enhance the convective mass transfer on the walls of a mass transfer flow system such as an electrodeposition cell, absorption column, flow reactor, etc. A number of experimental studies have been conducted to determine the distribution of the mass transfer coefficients on the bottom wall of a parallel-plate channel for the flow conditions with/without a pulse in the research. Here, the distribution of the convective mass transfer coefficients has been determined by the electrochemical limiting diffusion current technique (ELDCT) using nickel local cathodes arranged on the bottom surface of the flow channel. The experimental results show the effects of the parameters used, which are the flow Reynolds number, opened/closed (OP/CL) ratio, and pulse number, on the distribution of mass transfer coefficients. The results have revealed that the pulse generator altered the flow structure and increased the turbulent intensity at Re < 2860 flow conditions. Within the range of Reynolds number 950 < Re < 2860, the mass transfer correlation was given as $Sh=67.02{Re}^{0.897}{\left({\displaystyle \frac{Op}{Cl}}\right)}^{-0.059}S{c}^{1/3}$. According to the research findings, the highest k_M values were obtained at Re = 2860 with an (OP/CL) ratio of 1/2. If a parallel-plate flow reactor with a pulse generator is designed using these flow conditions, it will yield a reactor that is both more efficient and more compact than a reactor without a pulse generator.
