Summary

Direct-contact heat and mass transfer packing (or its alternative term, direct-contact heat and mass exchangers) are integral components in the cooling towers of thermal power plants and dryers. In cooling tower applications, such packings enable the efficient evaporation of water into an air stream using a counterflow configuration, thereby cooling the descending water. Moreover, such cooling towers find utility in the cooling of diesel engines or other engine systems.


Emerging innovations in the renewable energy sector, particularly those related to air-water thermal power plants, employ direct-contact heat and mass transfer packing to create a vapor-air mixture for power production, facilitating the use of low-temperature heat sources. In a parallel manner, packed beds are often utilized in direct-contact condensers, permitting the effective condensation of large amounts of water vapor within a small condenser volume.


In this Special Issue, we invite the submission of both research and review articles relevant to Direct-Contact Heat and Mass Transfer Packings and Packed Beds. Contributions may include experimental, semi-empirical, analytical, or computational studies. We specifically encourage submissions focusing on Packings and Packed Beds operating at higher temperatures.

    Abstract The goal of this work is, first of all, to construct a mathematical model of the mass transfer process in porous adsorption layers, taking into account the fact that in most cases the adsorption process is carried out in non-stationary technological modes, which requires a clear description of its various stages. The scientific contribution of the novel model is based on a probability approach allowing for deriving a differential equation that takes into account the diffusion migration of adsorbed particles. Solving this equation allows us to calculate the reduced degree of the adsorption surface coverage… More >
