This unique compendium revises the most recent thermodynamic theories of supercritical fluids, focusing on the dynamic crossover and the role of thermodynamic properties in controlling this crossover.The volume also critically discusses different transition criteria to predict the onset of single-phase (diffusive) mixing and applies them to transcritical droplets and jets. The book overviews the different types of disintegration regimes and the conditions under which phase separation made be observed, even for supercritical injection conditions.This useful reference text benefits professionals, researchers, academics and graduate students in the fields of aerospace engineering, applied physics, chemical engineering and energy studies.
