TL;DR: In this article, the hydrodynamic interaction between a regular porous medium and an adjacent free-flow channel at low Reynolds numbers was examined experimentally, and the results showed that, from a microscopic point of view, parallel flow at the interface is not obtained due to the periodically generated U-shaped flow profile between the interface pillars.
Abstract: This study examines experimentally the hydrodynamic interaction between a regular porous medium and an adjacent free-flow channel at low Reynolds numbers (Re < 1). The porous medium consists of evenly spaced micro-structured rectangular pillars arranged in a uniform pattern, while the free-flow channel features a rectangular cross-sectional area. The overall arrangement comprises a polydimethylsiloxane microfluidic model where distilled water, doped with fluorescent particles, is the examined fluid. Using micro-particle image velocimetry, single-phase quantitative velocity measurements are carried out at the pore scale to reveal the microscopic characteristics of the flow for such a coupled system. Interfacial velocity-slip and stress-jump coefficients are also evaluated with a volume-averaging method based on the Beavers-Joseph and Ochoa-Tapia-Whitaker models, respectively. The results show that, from a microscopic point of view, parallel flow at the interface is not obtained due to the periodically generated U-shaped flow profile between the interface pillars. However, the interface coefficients show no sensitivity to moderate flow angles. The highly resolved experimental information obtained in this study can also be used for the validation of numerical models providing a unique dataset for free-flow and porous media coupled systems.

TL;DR: In this article, a review of the state-of-the-art and new trends in developing efficient two-component composites for various AHT cycles is presented, including adsorption chilling, desiccant cooling, heat storage and regeneration of heat and moisture in ventilation systems.
Abstract: Adsorption heat transformation (AHT) is one of the challenging technical approaches for supporting the world community initiatives to alleviate or reverse the gravity of the problems arising from CO 2 emissions and global warming. The key tool for enhancement of the AHT efficiency and power is a harmonization of adsorbent properties with working conditions of the AHT cycles. It can be realized by means of target-oriented designing the adsorbent specified for a particular AHT cycle. Two-component composites ‘salt in porous matrix’ (CSPMs) offer new opportunities for nano-tailoring their sorption properties by varying the salt chemical nature and content, porous structure of the host matrix and synthesis conditions. CSPMs have been recognized as promising solid sorbents for various AHT cycles, namely adsorption chilling, desiccant cooling, heat storage and regeneration of heat and moisture in ventilation systems. In this review, we survey a current state-of-the-art and new trends in developing efficient CSPMs for various AHT cycles. Copyright , Oxford University Press.
