Flow Control and Optimization is increasingly incorporated in the design of engineering devices ranging from aircraft and space vehicles to micro?uidic devices. Research in this ?eld aims to integrate knowledge in ?ow physics with theoretical advances and novel experimental capabilities and engineering devices capable of materializing advanced design concepts. In turn controlled ?ow phenomena exhibit a new arrays of physics and open frontiers for further interdisciplinary research in ?uid mechanics and all the engineering domains that it a?ects. This collection of papers in ?ow control,...
