Plate Heat Exchanger Enhancement Techniques: in Support of the Energy Transition and a Circular Economy provides fundamental knowledge on the applications of the plate heat exchanger (PHE) and how it can be optimized to make energy conversion more efficient. In addition, it introduces relevant studies that explain the heat transfer mechanism of the PHE, its design, and how developing more compact and evolved heat exchangers contributes to a sustainable, cleaner, and more energy-efficient future. Researchers, scientists, engineers, professionals, and students working in nanotechnology, materials science, and sustainability will find this volume valuable to their work.
