<p>This book is a comprehensive and intensive book for graduate students in fluid dynamics as well as scientists, engineers and applied mathematicians. Offering a systematic introduction to the physical theory of vortical flows at graduate level, it considers the theory of vortical flows as a branch of fluid dynamics focusing on <i>shearing process </i>in fluid motion, measured by <i>vorticity</i>.</p><p>It studies vortical flows according to their natural evolution stages,from being generated to dissipated. As preparation, the first three chapters of the book provide background knowledge for entering vortical flows.</p><p>The rest of the book deals with vortices and vortical flows, following their natural evolution stages. Of various vortices the primary form is <i>layer-like vortices </i>or <i>shear layers</i>, and secondary but stronger form is <i>axial vortices </i>mainly formed by the rolling up of shear layers.</p><p> Problems are given at the end of each chapter and Appendix, some for helping understanding the basic theories, and some involving specific applications; but the emphasis of both is always on physical thinking.</p>
