The present book - through the topics and the problems approach - aims
at filling a gap, a real need in our literature concerning CFD
(Computational Fluid Dynamics). Our presentation results from a large
documentation and focuses on reviewing the present day most important
numerical and computational methods in CFD. Many theoreticians and
experts in the field have expressed their - terest in and need for such
an enterprise. This was the motivation for carrying out our study and
writing this book. It contains an important systematic collection of
numerical working instruments in Fluid Dyn- ics. Our current approach to
CFD started ten years ago when the Univ- sity of Paris XI suggested a
collaboration in the field of spectral methods for fluid dynamics. Soon
after - preeminently studying the numerical approaches to Navier-Stokes
nonlinearities - we completed a number of research projects which we
presented at the most important inter- tional conferences in the field,
to gratifying appreciation. An important qualitative step in our work
was provided by the dev- opment of a computational basis and by access
to a number of expert softwares. This fact allowed us to generate
effective working programs for most of the problems and examples
presented in the book, an - pect which was not taken into account in
most similar studies that have already appeared all over the world.
