This book presents a comprehensive overview of fluid mechanical, thermal and physico-chemical aspects of drop-surface interactions. Basic physical mechanisms pertaining to free-surface flow phenomena characteristic of drop impact on solid and liquid surfaces are explained emphasizing the importance of scaling. Moreover, physico-chemical fundamentals relating to a forced spreading of complex solutions, analytical tools for calculating compressibility effects, and heat transfer and phase change phenomena occurring during solidification and evaporation processes, respectively, are introduced in detail. Finally, numerical approaches particularly suited for modeling drop-surface interactions are consisely surveyed with a particular emphasis on boundary integral methods and Navier-Stokes algorithms (volume of fluid, level set and front tracking algorithms). The book is closed by contributions to a workshop on Drop-Surface Interactions held at the International Centre of Mechanical Sciences.

1969 marked the return of the Cryogenic Engineering Conference, now affiliated with the National Academy ofSciences through the Division ofEngineering, National Research Council, to the University of California at Los Angeles. As in 1962, the Cryogenic Engineering Conference gratefully acknowledges the assistance of UCLA, its Engineering and Physical Seien ces Extension Division, and in particular J. Dillon, S. Houston, H. L. Tallman, and their stafffor serving as hosts to the 1969 Cryogenic Engineering Conference. The National Academy of Sciences is a private honorary organization of more than 700 scientists and engineers elected on the basis of outstanding contributions to knowledge. Established by a Congressional Act of Incorporation, the Academy works to further science and its use for the general welfare by bringing together the most qualified individuals to deal with scientific and technological problems of broad significance. The National Research Council was organized as an agency of the National Academy of Sciences in 1916, to enable the broad community of U.S. scientists and engineers to associate their efforts with the Iimited membership of the Academy in service to science and the nation. The Division of Engineering is one of the eight major Divisions into which the National Research Council is organized for the conduct of its work. Its membership includes representatives of the nation's leading technical societies as weH as a number of members-at-Iarge. The Cryogenic Engineering Conference is an organization of the Division of Engineering.
