Mostafa Safdari Shadloo, National Institute of Applied Science, Rouen, France
Dr. Shadloo has been an Associate Professor, since Sept. 2015, at the National Institute of Applied Science (INSA), Rouen and a Researcher at Coria Lab. (CNRS-UMR 6614). Dr. Shadloo has been actively engaged in the fields of (i) (aero-) hydrodynamics, turbulence, transitional boundary layers, as well as (ii) multiphase, multi-physics fluid flows and heat transfer for the last 10 years. His expertise is mainly in theoretical and computational fluid dynamics (CFD), but he has also been active in developing validation strategies and guidelines for CFD. He aims to develop a new generation high-order coupled algorithm for compressible/incompressible fluid flows with complex physical behaviors in relation to industrial applications. In this framework, he uses high-performance computing (HPC), high-fidelity direct numerical simulations (DNS) and large-eddy simulations (LES) to decipher complex instabilities and flow behaviors caused mainly by multiphase and turbulent flows, with heat transfer and compressibility effects.

Summary

Frontiers in porous drying refer to the latest developments and advancements in the field of drying porous materials such as food, pharmaceuticals, and ceramics. Porous materials have a complex structure that makes their drying process challenging, and the frontiers in porous drying aim to address these challenges by developing new techniques and technologies for efficient drying. Some of the frontiers in porous drying include the use of advanced computational models, innovative drying technologies such as microwave and freeze-drying, and the development of new materials with improved drying properties. These frontiers are essential in improving the quality and shelf-life of porous products while reducing energy consumption and production costs.


Heat and mass transfer play a crucial role in the drying process of porous materials. Heat is required to evaporate the moisture content present in the pores of the material, while mass transfer is necessary to transport the evaporated moisture from the interior of the material to the surface, where it can be removed. The rate of heat and mass transfer determines the drying time and the quality of the final product.


The heat transfer mechanisms involved in drying include conduction, convection, and radiation. Conduction involves the transfer of heat from the surface of the material to its interior, while convection involves the movement of air or other gases over the surface of the material, which helps to carry away the evaporated moisture. Radiation involves the transfer of heat through electromagnetic waves. The mass transfer mechanisms involved in drying include diffusion and capillary action. Diffusion involves the movement of moisture from areas of high concentration to areas of low concentration, while capillary action involves the movement of moisture through small pores and channels within the material. Efficient heat and mass transfer is essential for achieving uniform drying and preventing over-drying or under-drying of porous materials. The development of new techniques and technologies for improving heat and mass transfer in porous drying is an important frontier in this field.


The main aim of this special issue is to provide a platform to show the latest progress of innovative and emerging drying technologies for enhancing food quality. High-quality research as well as comprehensive review papers on this topic are highly welcomed and recommended. We hope that this special issue not only contributes to a better understanding of the research status of innovative and emerging drying techniques, but also triggers new research opportunities in this field in order to provide more healthy and nutritious food for the growing global population in a more sustainable way.

    Abstract As a means of harvesting solar energy for water treatment, solar-driven vapor generation is becoming more appealing. Due to their entangled fibrous networks and high surface area, fibers can be used as building blocks to generate water vapor. In this paper, using a two-dimensional fiber bundle model, we studied the generation of solar vapor based on the fiber height, distance between fibers, and input sun radiation. The performance of solar absorption system was also evaluated by evaluating thermal and water management. Results showed a constant increase in solar vapor generation with an increasing fiber height and decreasing inter-fiber distance. However,… More >
