Special Issue "Non-Equilibrium Thermodynamics of Micro Technologies"
Deadline for manuscript submissions: closed (10 December 2018)
Miniaturized thermofluid systems have recently gained significant attention from theoretical and experimental viewpoints. This is, mainly, due to the increasing applications of these systems in micro manufactured devices. Recently, micro heat sink thermal systems, such as microchannels and microtubes, have been used for a wide range of thermal and biological purposes. Among these, microchannels filled with porous materials have received particular attention as they feature favorable characteristics for cooling and pumping technologies in biomedical engineering. Utilization of microchannels has further resulted in the development of the so-called ‘microreactors’ for chemical process intensification. These devices build upon the technological progress in the general fields of microchannels and micro-thermofluids to accommodate homogenous or heterogonous chemical reactions. Micro porous tubes have also been used for miniaturized cryocoolers. The applications of microreactors and miniaturized cryocoolers are now at their most extensive and include applications in combustion, hydrogen, cryogenic and syngas production and industrial chemicals. These devices can also involve multiple reactants and exothermic/endothermic stages. Therefore, they should feature very efficient mixing and heat transfer characteristics.
Second law analysis and entropy generation minimization have started to be employed in the design and optimization of various thermal and thermochemical systems. These include microchannels and microtubes with applications in micro thermal, mechanical, chemical and biological systems. Further developments in this front call for a more rigorous understanding and modeling of thermodynamic processes in micro devices under highly irreversible conditions.
This Special Issue aims to be the forum for the presentation of the novel non-equilibrium thermodynamic investigations in the broad area of micro-technology. In particular, heat and mass transfer and entropy generation investigations in microchannels, microreactors, microcryocoolers, and micro-thermofluids fall within the scope of this Special Issue.
