Sonin and published by . This book was released on 1965 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were performed in an RF generated, low density plasma flow to determine the behaviour of small, cylindrical Langmuir probes in high-speed flows. All mean free paths were large compared to the probe diameter except the mean free path for ion-ion collisions. The tests indicated that under simulated static conditions (probe axis parallel to flow velocity), the theory of Laframboise represented the ion current characteristic well when the ratio between radius of probe and Debye length was large, but not when the probe radius was comparable to or smaller than the Debye length. The results indicated clearly that the ion current decreased with increasing normal velocity, reached a minimum, and then increased again for subsequent increases in velocity. Subsequently, the probes were used in a study of the charged particle number density and electron temperature distributions in the stagnation region of a flat-nosed cylinder in supersonic flow. The electron temperature had a constant value throughout the bow shock and the entire shock layer. The charged particle number density distribution measurements provided a graphic demonstration of the merging of the bow shock and the boundary layer at a value of Reynolds number of about 100, and also furnished evidence of the diffusive separation of the ions and atoms in the shock wave. Independent measurements of the ion flux to the stagnation point wall were in good agreement with the Langmuir probe measurements in the shock layer.

Book excerpt: A theoretical and experimental investigation of the response of a free molecule Langmuir probe in a turbulent plasma is made. The effect of arbitrary fluctuations in charged particle density, electron temperature, plasma potential, and ion temperature are considered. The results are applicable for (a) frequencies somewhat less than the ion plasma frequency, (b) moderate ratios of probe radius to Debye length, (c) moderate ratios of applied potential to electron temperature and (d) ratios of ion to electron temperatures less than one. The steady state characteristic is obtained by forming an empirical fit to a numerical analysis describing the collisionless probe current collection. Relations are then derived showing the effect of fluctuations on the average properties, and the connection between the r.m.s. probe current and the various correlations. Electron temperature, charged particle density, floating potential, single probe saturation ion and electron current and double-probe current measurements are studied in detail. It is found that the sensitivity of the probe to the various fluctuating quantities is a function of the ratios of probe radius to Debye length, applied potential to electron temperature, and ion to electron temperature. Subsequently it is shown that many of the correlations and average properties may be determined. Experiments are performed in an unsteady highly expanded low density flowing argon plasma. Both the average and r.m.s. currents are monitored using cylindrical Langmuir probes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Aeronautical Sciences, Volume 10 provides information pertinent to the development in aeronautical sciences. This book discusses a variety of topics, including thermoelasticity, turbulent boundary, as well as the manufacturing methods, reliability, problem areas, and applications under development in fluidic systems. Organized into six chapters, this volume begins with an overview of the theoretical problems of elasticity. This text then discusses the state of research in the complex fields of turbulent boundary layers with fluid injections. Other chapters consider as well the problems of supersonic flow past wings and bodies. This book discusses as well the flow in hypersonic wakes in ionized gases. The reader is also introduced to the possible applications of the compressible turbulent boundary layer with fluid injection. The final chapter discusses the components used in fluidic systems, which are described with emphasis on their general system of operation and general properties. This book is a valuable resource for engineers.
