This book investigates the unique hydrodynamics and heat transfer
problems that are encountered in the vicinity of the critical point of
fluids. Emphasis is given on weightlessness conditions, gravity effects
and thermovibrational phenomena. Near their critical point, fluids
indeed obey universal behavior and become very compressible and
expandable. Their comportment, when gravity effects are suppressed,
becomes quite unusual.
The problems that are treated in this book are of interest to students
and researchers interested in the original behavior of near-critical
fluids as well as to engineers that have to manage supercritical fluids.
A special chapter is dedicated to the present knowledge of critical
point phenomena. Specific data for many fluids are provided, ranging
from cryogenics (hydrogen) to high temperature (water). Basic
information in statistical mechanics, mathematics and measurement
techniques is also included. The basic concepts of fluid mechanics are
given for the non-specialists to be able to read the parts he is
interested in. Asymptotic theory of heat transfer by thermoacoustic
processes is provided with enough details for PhD students or
researchers and engineers to begin in the field. Key spaces are
described in details, with many comparisons between theory and
experiments to illustrate the topics.
