We compare the performance of five hygrometers fitted to the Facility for Airborne Atmospheric Measurement’s (FAAM) BAe 146-301 research aircraft using data from approximately 100 flights executed over the course of 2 years under a wide range of conditions. Bulk comparison of cloud free data show good agreement between chilled mirror hygrometers and a WVSS-II fed from a modified Rosemount inlet...

A wetting and drying (WAD) algorithm is implemented in a baroclinic three-dimensional ocean circulation model of Cook Inlet, Alaska, where large tidal ranges (≈10 m) regularly expose extensive mudflats. The model includes tides and windand buoyancy-induced flows. In the upper Inlet, the model successfully simulates large amplification of tides and propagation of fast (3∼4 m s) tidal bores over ...

The influence of the inlet swirl velocity profile shape on the decay of swirl in steady-state, incompressible, laminar pipe flows is investigated by means of computational fluid dynamics. The investigation is carried out for a Reynolds number of 2000, which marks the upper limit of the laminar flow behavior for unidirectional pipe flow. Computations are performed for two different mean swirl nu...

1964 B E C K E Y reported about a combined field ionisation/electron impact source1 the commercial version of which is shown in Fig. 1 2. Vhe vapour to be analyzed enters the source via an inlet line. However such inlet is suitable only for sampes of not too low volatility. For the qualitative analysis of organic compounds of very low volatility evaporation out of an oven (direct inet) in the i...

The internal working processes in pulse tube cryocooler (PTC) are quite complex due to the unsteady, oscillating compressible gas flow in the pulse tube. Although considerable theoretical studies have been carried out as of date phenomena occurring in a pulse tube cryocooler are still to be understood. The present research work is carried out in order to understand the cooling mechanism and to ...

The National Marine Fisheries Service (NMFS) conducted aerial surveys of the beluga, Delphinapterus leucas, population in Cook Inlet, Alaska, 31 May 9 June 2011 as a continuum of surveys conducted since 1993. Eight of the days in 2011 resulted in complete surveys of the beluga habitat in the upper inlet (north of East Foreland and West Foreland); and the remaining two days included surveys of t...

This study investigates the effect of air inlet size on (i) the flowfield generated in a dry powder inhaler, and (ii) the device-specific resistance, and the subsequent effect on powder deagglomeration. Computational fluid dynamics (CFD) analysis was used to simulate the flowfield generated in an Aerolizer with different air inlet sizes at 30, 45, and 60 l/min. Dispersion performance of the mod...

In the present investigation the distribution of mean velocity, static pressure and total pressure are experimentally studied on an annular curved diffuser of 37.5° angle of turn with an area ratio of 1.284 and centerline length was chosen as three times of inlet diameter. The experimental results then were numerically validated with the help of Fluent and then a series of parametric investigat...

The objective of this work is to investigate the turbulent reacting flow in a three dimensional combustor with emphasis on the effect of inlet swirl flow through a numerical simulation. Flow field is analyzed using the SIMPLE method which is known as stable as well as accurate in the combustion modeling, and the finite volume method is adopted in solving the radiative transfer equation. In this...
