The special issue, titled “Entropy Generation Due to Nanofluid Flow in Porous Media, Micro/Mini Channels, and Cavities,” encompasses ground-breaking research at the convergence of nanofluid dynamics, magneto-convective flow, interactions within porous media and entropy generation. This collection not only highlights the intellectual vibrancy within our academic community but also mirrors the careful selection process we implemented to maintain rigorous academic standards.
Context of the call for papers: Our call for papers aimed to harmonise two critical research streams: nanofluid flow in micro/mini channels and cavities and the intricate dynamics within porous media. The overarching objective was to distil collective knowledge to make informed design decisions in microdevice thermal management, particularly in scenarios such as the rapid cooling of high heat-flux microdevices. The call highlighted the need for robust research to address challenges and enhance thermal control in microdevices deploying nanofluids.
Incorporating thermal irreversibility and entropy generation: Our comprehensive exploration of the concept of irreversibility, meticulously quantified through the entropy generation term, plays a pivotal role in delving into the nuanced “generation of irreversibility.” This strategic approach is intricately aligned with our steadfast commitment to advancing the comprehension of fluid behaviour and entropy generation within intricate systems.
Fusion of thermal irreversibility with a focus on work opportunity loss: With a keen emphasis on the loss of work opportunity, our seamless integration of thermal irreversibility draws profound inspiration from Witte and Shamsundar’s insightful analogy dating back to 1983. This conceptual fusion has been further elucidated in the recent paper titled “Thermal Irreversibility Demystified” [1]. Within this paper, we introduce an alternative visualisation for heat transfer, offering profound insights into the forfeited work opportunity during the process across a temperature difference. This novel perspective significantly contributes to our understanding of irreversibility, adding depth to the discourse.
Rigorous review process and selectivity: The special issue maintains its academic integrity through a rigorous review process. Each submission underwent meticulous evaluation, resulting in a commendable acceptance rate of 28%. This judicious acceptance rate attests to the high quality and relevance of the selected contributions, a testament to the commitment of our scholarly reviewers.
