In the present work, the spray characteristics of kerosene and ethanol blends discharging from a pressure-swirl nozzle are experimentally studied in the spray chamber
under ambient temperature and pressure conditions.
By additional temperature cycles, salt spray chamber
can be used to replicate conditions encountered at cold end in a real driving cycle.
A similar study using a constant volume spray chamber
with optical access called Cetane Ignition Delay (CID) has been also reported [5,6], where the end of the physical delay and the start of the chemical delay is defined when excited CH20* chemiluminescence, a low temperature heat release indicator, is first observed.
For instance, the salt spray chamber
ensures that the products coated with Manifa powder are truly the best in the market.
Abstract: This paper presents aging tests on BGA assemblies in a salt spray chamber
. The test vehicle is composed of BGA components with SAC balls mounted on FR-4.
The combination of the preeflow positive displacement volumetric pump and a low-flow spray chamber
guarantees high performance spraying of low to high viscosity fluids.
Nebulizer: Glass concentric Spray chamber
: Glass cyclonic RF power: 1600 W Nebulizer flow: Optimized for <2% oxides Mode: Standard Isotope: 75As Dwell time: 500 ms Sampling rate: 2 points/sec
White rust was developed and visible to the naked eye after an exposure of 72 h in the salt spray chamber
. White rust on sol-gel coated substrate with 0.75% zirconyl nitrate was developed after 68 h.
b) coating systems artificially weathered using salt spray chamber
The visualization system used in this experiment was composed of a high speed digital camera and spray chamber
side illumination arrangements.
ELSDs use patented thermo-split technology to precisely control the spray chamber
and drift tube temperatures, thereby optimizing detector sensitivity over a range of flow rates and gradients.
