This book provides a hybrid methodology for engineering of trickle bed reactors by integrating conventional reaction engineering models with state-of-the-art computational flow models. The content may be used in several ways and at various stages in the engineering process: it may be used as a basic resource for making appropriate reactor engineering decisions in practice; as study material for a course on reactor design, operation, or optimization of trickle bed reactors; or in solving practical reactor engineering problems. The authors assume some background knowledge of reactor engineering and numerical techniques.
- Facilitates development of high fidelity models for industrial applications
- Facilitates selection and application of appropriate models
- Guides development and application of computational models to trickle beds
Chemical engineers working in industry (chemical companies, industrial research laboratories), chemical engineering scientists and research students working in the area of reactor engineering

Vivek V. Ranade
Dr Vivek Ranade is a Bernal Chair Professor of Process Engineering at Bernal Institute, University of Limerick, Ireland. He leads ‘Multiphase Reactors and Process Intensification’ group. Vivek and his group use experiments, computational flow modelling, population balance models and machine learning to generate new insights in multiphase flows, multiphase reactors, and process intensification. The group is developing novel fluidic devices, intensified processes and ‘factory in a box’ platforms for decentralised manufacturing, personalised products, responsible resource usage, decarbonisation as well as mitigation and valorisation of waste.
