Journal ArticleDOI
Thermal conductivity of packed beds: A review
Evangelos Tsotsas,Holger Martin +1 more
TL;DR: The voluminous literature available on thermal conductivities of packed beds without fluid flow is reviewed in this article, including experimental methods as well as theoretical approaches, and a classification of predictive models is attempted.
Journal ArticleDOI
A simple and coherent set of coefficients for modelling of heat and mass transport with and without chemical reaction in tubes filled with spheres
TL;DR: In this paper, the authors conducted a comprehensive reevaluation of available experimental work with spherical particles and presented a simple and consistent set of coefficients based on an uneven flow distribution and on a wall heat conduction model (Λr(r)-model).
Journal ArticleDOI
Microencapsulation of walnut oil by spray drying: Effects of wall material and drying conditions on physicochemical properties of microcapsules
Samira Shamaei,Seyed Sadegh Seiiedlou,Mortaza Aghbashlo,Evangelos Tsotsas,Abdolreza Kharaghani +4 more
TL;DR: In this article, the effects of wall material formula and spray drying conditions on physicochemical properties of walnut oil microcapsules were investigated, where three different wall materials including skim milk powder (SMP), SMP+Tween 80, and SMP−maltodextrin were used for emulsion preparation.
Journal ArticleDOI
Methods for processing experimental drying kinetics data
Ian C. Kemp,B. Christran Fyhr,Stéphane Laurent,Michel A. Roques,Carda E. Groenewold,Evangelos Tsotsas,Alberto A. Sereno,Cathenne B. Bonazzi,Jean-Jacques Bimbenet,Mathhues Kind +9 more
TL;DR: In this paper, a review of methods for processing the data obtained from drying kinetics rigs and pilot-plant trials is presented, aiming to generate curves that are usable in industrial design without losing vital information by oversmoothing.
Journal ArticleDOI
Heat transfer in packed beds with fluid flow: remarks on the meaning and the calculation of a heat transfer coefficient at the wall
TL;DR: In this paper, it was shown that for small values of the molecular Peclet number no resistance at the rigid wall exists, and that the effect of lateral maldistribution of fluid velocity and/or thermal conductivity, of axial dispersion of heat, and of small, systematic errors in measurement is investigated.
