Title: Solid H2/D2 Particle Seeding and Injection System for Particle Image Velocimetry (PIV) Measurement of He II

Abstract

Solid particles of the mixture of hydrogen and deuterium have certain advantages for use in Particle Image Velocimetry (PIV) of He II flow. The H2/D2 particles are near neutrally buoyant in He II and will vaporize with the helium as the experimental apparatus is warmed to room temperature. Progress of the construction of a H2/D2 particle seeding and injection system is reported in this paper. A cryogenic pulse valve is used to inject the mixture of helium, hydrogen and deuterium gas directly into a He II bath. Experiments show that the seeding quality is dependent on the back pressure, the mix ratio of the deuterium and helium gases and valve open duration. The effects of these parameters on the solid deuterium particle distribution are also discussed.

  • Particle image velocimetry (PIV) was used to study air flow characteristics at the outlet of an automotive supercharger. Instantaneous velocity fields were analyzed to yield ensemble-averaged velocities and Reynolds stresses, and the ensemble-averages were used to determine maximum velocity and exit flow angle as a function of blade position for various speeds and pressure ratios. The results show that the flow exits the supercharger as a high-speed jet that not only varies in the parallel plane but also in the perpendicular plane, generating a complex three-dimensional flow. The flow varies in the magnitude and the angle at which it leavesmore » the supercharger with the change in blade position and follows a periodic behavior. The maximum velocity at which the flow exits the supercharger also follows a periodic behavior with a variation of 25-30% observed for all the cases. In the parallel plane, the exit angles are periodic every 60 deg of blade rotation and vary by as much as 40 deg, whereas periodic behavior with every 120 deg of blade rotation and a variation of 60 deg is observed in the perpendicular plane. Variation in flow with blade position is also observed in the velocity and turbulence profiles, with periodic behavior with every 60 blade rotation. The velocity and velocity fluctuation profiles show that the unsteady nature of the flow is most significant close to the outlet, and these unsteady variations diminish 58 mm downstream of the outlet. An exit flow pattern of a figure 8 is generated as the flow leaves the blades with one complete blade rotation of 120 for all the cases, except 4000 rpm, pressure ratio 1.4, where the flow exits in a circular pattern.

  • Particle Image Velocimetry (PIV) is a fluid measurement technique in which the average displacement of small groups of particles is made by comparing a pair of images that are separated in time by an interval {Delta}t. For over a decade, a several variations of the PIV technique, e.g., two-dimensional, stereoscopic, and tomographic PIV, have been used to characterize particle transport, instabilities, and the thermal properties of complex plasmas. This paper describes the basic principles involved in the PIV analysis technique and discusses potential future applications of PIV to the study of complex plasmas.
  • Solid H{sub 2}, D{sub 2} and H{sub 2}/D{sub 2} particles can be generated in He II by solidifying directly from the gas phase. Here we compare these three different particles as tracers for tracking He II forced flow in a horizontal channel using the Particle Image Velocimetry (PIV) technique. Slip velocity measurements show that all generated particles are in the micron size range. Steady state velocity fields of the forced flow of He II within a square cross-section channel are measured. By comparing the results obtained from different tracers, we show that the slip velocity caused by non-neutral buoyancy ofmore » these particles does not affect the measured velocity profiles of He II forced flow.« less
  • Use of high-image-density particle image velocimetry (PIV) allows characterization of the instantaneous structure of wake and wake-blade interactions in a simulated rotating machine. The distribution of vorticity over an entire plane within the pumping system is related to the instantaneous pressure source terms in the wake of the impeller. Comparison of instantaneous and ensemble-averaged vorticity contours shows that limited ensemble-averaging can produce a substantial reduction in vorticity levels associated with the instantaneous pressure source terms. When the wake from the impeller interacts with a stationary diffuser blade, the instantaneous processes of flow separation and reattachment can be effectively characterized usingmore » combinations of instantaneous streamline patterns and contours of constant vorticity. Moreover, active control of the inflow into the pumping system allows substantial modification of these vorticity distributions.« less
  • Formation of stable CH5(+) and CD5(+) has been studied in a liquid nitrogen cooled radio-frequency (RF) ion trap. Ternary rate coefficients, k3, have been measured for He, H2, and D2 as the stabilizing collision partner. The results for He are in satisfying agreement with SIFT data. The experiments have been performed at very low densities permitting information to be extracted on the radiative association process. Because both k3 and the radiative rate coefficient k(r) are observed under the same experimental conditions, comparison leads to a reliable upper limit of the radiative stabilizing rate of the intermediate CH5(+) collision complex. Themore » results are significantly smaller than the values currently discussed in the literature, but they are in accord with infrared relaxation rates measured directly for highly excited CH5(+) ions. Using two different mixtures of p-H2 and o-H2 at 80 K, the influence of the H2 rotational energy was determined. The derived ratio is four times smaller than predicted from theoretical work. 30 refs.« less
