In this book, experts provide recent developments in scientific findings and technologies, and introduce new theoretical models concerning mass transfer for sustainable energy and environment. The expertise of mass transfer processes has been extended and applied to different realm of science and engineering, including industrial applications in recent years. Since mass transfer is a primeval phenomenon, it plays a vital role in the scientific researches and fields of mechanical, energy, environmental, materials, bio and chemical engineering. The chapters have been grouped under a section advances in numerical analysis and measurement. The topics cover the developments in broad research areas, hence, the book will be informative not only to research engineers, but also to university professors and students.
