The papers in this volume are mostly in the area of computational fluid dynamics (CFD). Furthermore, to some extend this volume contains also contributions from the field of new experimental mehtods and diagnostics applied to fluid dynamics, combustions and turbomachniery. the contributed papers cover diverse topics such as pipe flows, shock tube flows, compressor flows as well as velocity and turbulence measurements of flow conditioners. There is also a survey article on recent flow computations on high performance computers. Articles are also devoted to liquid-liquid systems, rotating fluid flows and combustion diagnostics.
