Plate Heat Exchanger Enhancement Techniques: in Support of the Energy Transition and a Circular Economy lays out the basics and provides fundamental knowledge on the applications of the plate heat exchanger (PHE) and how it can be optimized to make energy conversion more efficient and improve the economy. This reference 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, particularly on reuse and end-of-life materials from renewable sources, will find this volume, written by a global panel of experts, valuable to their work and ensuring their pursuit of the shared goal of clean, affordable energy.
