  • Vaccinia Virus and Poxvirology
    Exhaled gases and the noninhaled aerosol exit the individual exposure stations via an exhaust plenum through a .... The impinger outlet is connected to an inline HEPA filter and exhausts through a vacuum pump, which pulls the aerosol through the … when the input air pressure is set at 18 psi and a 5-L flow restrictor is in place.
  • Field Measurement of the Fate of Atmospheric H 2 in a Forest Environment: from Canopy to Soil
    The pressure trans- ducer, flow controller, and temperature probe were controlled and/or read through spare channels on .... A restrictor and a 2-way valve were placed on the H 2 standard line; the restrictor was used to match the calibration pressure to sam- ple pressures and the 2-way valve prevented the loss of calibration gas during power failures. .... by outer high-density polyethylene and an inner teflon layer, were installed with inline PFA filter holders…
  • Eddy Covariance
    Inlet and in- line filter are designated by F1 and F2. .... Two-way valves (shutoff) on the calibration gases , indicated by S2, select which calibration gas is in .... Flow adjusters/ restrictors are designated by green triangles.
  • Combustion Optimization in a Hydrogen-Enhanced Lean-Burn SI Engine
    As the swirl behavior of the 2/3 asymmetric restrictor plate and the tumble behavior of the tumble cone both demonstrate, flow will tend toward an even distribution after exiting a restriction. .... head is a modified Volvo B5254 (a single cylinder segment of an original inline five cylinder head.). .... with two types of fuel systems; one for liquid gasoline and the other for plasmatron reformate gas .
  • Improvement of Intake Restrictor Performance for a Formula SAE Race Car through 1D & Coupled 1D/3D Analysis Methods
    A one-dimensional gas exchange simulation code coupled with three-dimensional CFD is used to simulate various concepts in the improvement of restrictor performance. .... WAVE to determine if restrictor performance could be improved by attempting to make flow at the throat .... Inline Helmholtz resonators were also investigated in an attempt to increase pressure upstream of the throat.

  • PD 15(3) Measures to Reduce the Emission of Noise from Open-Air Plants in Refineries and Petrochemical Installations
    The noise reduction of inline silencers are in the range of 10to 20 dB (A). .... Low-noise valves are designed in such a manner that the gas or steam expansion phase is dragged locally and temporarily, so that the rate of flow and the discharge velocity are sufficiently lower than the velocity of sound, since shock waves .... A characteristicof this valve is an abrupt extension of the crosssectionbehind the restrictor instead ofthe usual gradual…
  • Evaluation of the Suitability of a Single-Cylinder Engine for Use in FSAE
    The silencer is modelled as five inline plenums, as advised in [9]. .... The flow of gas through all engines, and single-cylinder engines in particular, is inherently unsteady. .... However, to minimize the airflow limiting effects of the restrictor , steady flow across this device is desired.
  • High efficiency packed column supercritical fluid chromatography of sulfonylurea herbicides and metabolites from large water samples
    To interface the NPD and ECD into the column ef- fluent, zero-dead-volume (ZDV) tees were installed in- line after the column and before the UV detector. .... cm long, 50 gm inner diameter, 192 gm outer diameter fused silica flit restrictor [23] was slipped .... Only a small portion of total flow went to each of these detectors. .... ECD and the NPD were operated at 260 ~ The ECD make-up gas was 60 ml…
