    序言

    This book is primarily intended as a graduate text on turbulent flows forengineering students,but it may also be valuable to students in atmosphericsciences,applied mathematics,and physics,as well as to researchers andpracticing engineers.
    The principal questions addressed are the following.
    (i) how do turbulent flows behave?
    (ii)HOW can they be described quantitativelv?
    (iii)What are the fundamental physical processes involved?
    (iv)HOW can equations be constructed to simulate or model the behaviorof turbulent flows?In 1 972 Tennekes and Lumley produced a textbook that admirably ad. dresses the first three of these questions .In the intervening years. due inpart to advances in computing,great strides have been made toward pro-viding answers to the fourth question. Approaches such as Reynolds-stressmodelling,probability-density-function(PDF)methods,and large-eddy sim-ulation(LES)have been developed that,to an extent,provide quantitativemodels for turbulent flows.Accordingly,here(in Part II)an emphasis isplaced on understanding how model equations can be constructed to de.scribe turbulent flows:and this objective provides focus to the first threequestions mentioned above(which are addressed in Part I).However,incontrast to the book by Wilcox f1993),this text iS not intended to be apractical guide to turbulence modelling.Rather,it explains the concepts anddevelops the mathematical tools that underlie a broad range of approaches.There iS a vast literature on turbulence and turbulent flows,with manyworthwhile questions addressed by many difierent approaches.
