The journal covers a wide range of topics, including traditional and modern approaches to understanding and solving problems in these areas, as well as emerging technologies and applications. The journal aims to provide a forum for the exchange of ideas and knowledge among researchers, practitioners, and engineers working in the field of thermofluid research.</p> IREEE Press en-US International Journal of Advanced Thermofluid Research 2455-1368 https://www.ijatr.org/index.php/journal/article/view/34 <p>&nbsp;&nbsp;</p> Copyright (c) 2022 IREEE Press 2021-06-26 2021-06-26 7 1 1 2 https://www.ijatr.org/index.php/journal/article/view/35 <p>With historical roots linked to life sciences, species diffusion has inspired dynamic models for infectious disease spreading. However, drawbacks have been raised towards the inclusion of people’s displacement effects, whose ordered motion might refer to species convection within transport phenomena perspective. By transcending usual geometric role of spatial coordinates, the present work proposes a surrogate mathematical description via dimensionless generalized coordinates as intended to categorize people, whether or not infected, in terms of age and comorbidities. Accordingly, while diffusive infection refers to random motion of categorized people, convective infection can be additionally invoked and assigned to “streamwise” (i.e., ontology-driven) people’s motion. With infected-people fraction as dimensionless dependent variable, the governing partial differential equation equally considers source and sink terms referring respectively to contamination-reinfection and recovery-death rates. Such epidemic transport model is preliminary applied to SARS-CoV-2 spreading (i.e., COVID-19 dynamics) among categorized people and trial numerical simulations are performed in view of extant infection data from Florida (USA), here taken as case study. Prospective extensions for the proposed epidemic transport model are addressed (e.g., diffusive infection in inhomogeneous media and human’s displacement rheology).</p> José A.
