FLUID DYNAMICS AND TRANSPORT OF DROPLETS
AND SPRAYS
Second Edition
This book serves as both a graduate text and a reference for engineers
and scientists exploring the theoretical putational aspects of
the fluid dynamics and transport of sprays and droplets. Attention is
given to the behavior of individual droplets, including the effects of
forced convection due to relative droplet–gas motion, Stefan convec-
tion due to the vaporization or condensation of the liquid, -
ponent liquids (and slurries), and internal circulation of the liquid. This
second edition contains more information on droplet–droplet interac-
tions, the use of the mass-flux potential, conserved scalar variables,
spatial averaging and the formulation of the multicontinua equations,
the confluence of spatial averaging for sprays and filtering for tur-
bulence, direct numerical simulations and large-eddy simulations for
turbulent sprays, and high-pressure vaporization processes. Two new
chapters introduce liquid-film vaporization as an alternative to sprays
for miniature applications and a review of liquid-stream distortion and
breakup theory, which is relevant to spray formation.
William A. Sirignano is the Henry Samueli Professor of Mechanical
and Aerospace Engineering and former Dean of the School of Engi-
neering at the University of California, Irvine. Before that, he was the
e Tallman Ladd Professor and Department Head at Carnegie-
Mellon University and a professor at Princeton University. His major
research and teaching interests include bustion, turbulent
combustion and ignition, aerospace propulsion, fluid dynamics, and
applied mathematics. Dr. Sirignano has written more than 450 research
papers, book articles, and reports and has given more than 300 confer-
ence presentations and research seminars. He has been a formal con-
sultant to 30 anizations and federal laboratories.
Sirignano is a member of the National Academy of Engineeri
