Fluid Mechanics at Interfaces 1. Группа авторов

its vapor vanishes when passing the critical point. The piston effect replaces the conductive transfer of heat in the vicinity of solid walls in a 1D configuration.

      Chapter 5 (D. Beysens) examines shearing that causes Brownian motion anomalies in particles immersed in fluids that are undergoing strong fluctuations close to their critical point.

      Chapter 6 (R. Prud’homme) introduces basic concepts related to combustion interfaces. We also examine turbulent and laminar diffusion and premixed gas flames. A brief introduction to the Burke–Schumann problem is given and discussed, along with the calculation of the combustion rate of a thin premixed flame. The question of the combustion of solids such as thermites, plates with parallel flow and solid propellant rockets is also discussed. The appendices include a brief presentation of the Rankine–Hugoniot theory and a historical note on the research carried out in the field of combustion.

      The second volume, subtitled Case Studies and Instabilities, is devoted to the study of the applications to one-, two- and three-dimensional spaces, gaseous and liquid physical states, supercritical fluids and single- or multi-phase systems that may be pure or mixed.

      We will study the turbulence in discrete mechanics, atomization under an acceleration field, numerical simulations of tubes with sudden contraction, the evaporation of drops subjected to High Frequency disturbances, possible causes of instabilities in injection engines and flow in a Savonius wind turbine.

      This series may seem a little eclectic in its study of different themes in such a vast field, and the topics are, indeed, quite diverse. However, the contents are determined by the release of articles from the OpenScience journal. We hope, of course, that other volumes will be published that will complement this diversity, and, indeed, we wish to address other themes that may be missing here, such as foam, solidification of metals or alloys, plasma in two-phase media, four-dimensional interfaces (if we consider space-time and electromagnetic fields) and so on.
