Special Issue Information

Dear Colleagues,

In this Special Issue, entitled “Heat and Mass Transfer in Porous Materials”, we will present achievements in experimental and computational studies of combined heat and mass transfer in porous media through the use of modern physical methods and models.

This problem is considered as one of the complex and significant fundamental courses of modern science and has important applied relevance.

Original documents are requested for all scientific advances in the study of physicochemical processes in porous media.

For instance, this includes studies of heat and mass transfer processes in:

heat pipes (micro-heat, sorption and pulsating heat pipes with longitudinal grooves, micro- and nanoscale porous coatings, long heat pipes, vapourdynamic thermosyphons, etc.); in sorption cooling or heating systems; in mini-channels with porous nanocoating; in catalytic systems based on metals and metal-oxide porous materials, etc.

We also welcome studies on heat transfer enhancement in heat exchanger mini- and micro-channels, and on the practical use of heat pipes and thermosyphons.

Recent developments in the optimization of the platelet structure of materials used in various branches of technology for heat and mass transfer processes in porous spaces saturated with liquid or gas (evaporation, condensation, capillary transport, etc.) are of special interest.

Articles and reviews on the study of the internal mechanisms of mass and energy transfer in porous media, including predictions and efficiency assessment of porous materials used in various branches of engineering and technology, would be an asset.

This article introduces a novel analytical equation for computing the Nusselt number within the macroporous structures of channel absorbers utilized in high-temperature solar receivers. The equation incorporates heat and mass transfer processes occurring within boundary layers as fluid flows through complex-shaped macroporous absorber channels. The importance of accounting for the length of the thermodynamic boundary layer within channel-type macroporous media when calculating heat transfer coefficients using the Nusselt equation is demonstrated. By incorporating proposed indicators of porosity and flow characteristics, this method significantly enhances the accuracy of heat transfer coefficient calculations for such media. Discrepancies observed in existing calculation relationships and experiments are attributed to the omission of certain proposed values in the Nusselt number for macroporous media. To address this, empirical coefficients for the Nusselt number are derived using statistical methods. The resulting semi-empirical equation is applied to macroporous absorbers in solar receivers. The findings enable more accurate predictions of future absorber characteristics, enhancing their efficiency. The derived equation is successfully validated against numerical data across various geometric structures of absorbers in concentrated solar power plants. Full article

The article presents studies of the influence of parameters of synthesis modes and alkali concentration on the synthesis of zeolite materials from coal fly ash (CFA). The purpose of the study was to synthesise zeolite materials from CFA using the method of alkaline fusion and to determine the susceptibility of selected heavy-metal ions to removal from solutions in an ion exchange process on a selected mesoporous zeolite. It was found that the crystalline phase of sodalite was dominated in all of the samples synthesized. The specific surface area (SBET) of the samples was evaluated using the standard Brunauer–Emmett–Teller (BET) method using N2 sorption. Crystalline zeolite materials have been used to study the efficiency of removing heavy metals from aqueous solutions of Ni2+, Cd2+ and Pb2+. The adsorption data were analyzed using the Langmuir and Freundlich isotherm model. When comparing the estimated coefficient of determination (r2), it was noticed that the sorption data are more accurately described by the Langmuir isotherm and the pseudo-second-order kinetic model. The results of metal adsorption experiments suggest that the synthesized zeolite material has great potential to be used as an inexpensive and alternative source in the production of adsorbents.
