Is the heat and mass transfer intensification defined as a new paradigm of process engineering, or is it just a common and old idea, renamed and given the current taste ? Where might intensification occur ? How to achieve intensification ? How the shape optimization of thermal and fluidic devices leads to intensified heat and mass transfers ? To answer these questions, Heat & Mass Transfer Intensification and Shape Optimization : A Multi-scale Approach clarifies the definition of the intensification by highlighting the potential role of the multi-scale structures, the specific interfacial area, the distribution of driving force, the modes of energy supply and the temporal aspects of processes.
A reflection on the methods of process intensification or heat and mass transfer enhancement in multi-scale structures is provided, including porous media, heat exchangers, fluid distributors, mixers and reactors. A multi-scale approach to achieve intensification and shape optimization for maximization of performance with minimization of global impact of dissipations is developed and clearly explained.
Providing readers with a tool box of reflections, techniques, methods, supported by literature reviews, Heat & Mass Transfer Intensification and Shape Optimization : A Multiscale Approach will be a key guide for students, a teaching aid for lecturers and a source of inspiration for future research subjects.
