His research interests include systems involving multiphase fluid-particle flows, e.g., granulation, mills, spouted beds, rotary drums, solid and liquid separation, etc., through experiments and numerical simulations using the Euler-Euler, and the Euler-Lagrange approaches.Suellen Mendonça is an Adjunct Professor at Federal University of Lavras (UFLA), Brazil, since 2018. She graduated in Chemical Engineering (2013), MSc in Chemical Engineering (2014), and Ph.D. in Chemical Engineering (2018) from the Federal University of Uberlândia (UFU), Brazil. Her research interests include fluid dynamics of particulate systems, e.g., rotary drums with flights, rotary dryers and spouted beds, through experiments and numerical simulations using Computational Fluid Dynamics (CFD) and Discrete Element Method (DEM).

“This book provides a comprehensive overview of the existing literature and recent advances in the design, dimensioning, and modelling of rotating drums. It covers the main operating parameters, geometric configurations, and offers a useful compilation of design equations in Chapter 2, establishing a strong theoretical foundation and understanding of operating principles. Chapter 3 explores the development of novel configurations aimed at improving performance, including the innovative “roto-aerated” rotating dryer, which has been successfully applied in processing fruit residues. Chapter 4 focuses on modelling fluid dynamics, heat transfer, and mass transfer within rotating drums. The CFD and DEM numerical simulations provide insights into physical phenomena crucial for scale-up and process optimization. Both distributed and lumped parameter models are applied to describe drying processes in rotating drums. The content of this book is engaging to chemical, mechanical, and food engineers working in both research and industry.” - Maria do Carmo Ferreira, Chemical Engineering Department, Federal University of São Carlos, São Paulo, Brazil
