Theoretical Limits of Errors Due to Anisokinetic Sampling of Particulate MatterTheoretical estimates of errors in calculated concentrations of particulate matter, sampled with aspirated nozzles under conditions of anisokinetic flow, were based on computed trajectories of particles in fluid streams. In the...
Its design allows a variable fraction of the filtered emission gas to be added to the sample upstream of the inertial sizing device in order to maintain a preselected flow rate through this device while the gas flow rate into the sampling nozzle is adjusted to remain isokinetic with the local...
isokinetic sampling probeHorizontal turbulent water vapour (steam) jets were discharged into ambient air from a circular convergent nozzle under unchoked/choked and saturated/superheated nozzle exit conditions, resulting in two-phase (liquid and vapour), two-fluid (air and water) condensing free jets...
Significance and Use5.1 This practice describes the maximum transit-rate ratiosand depths that can be used for selected isokinetic suspended-sediment sampler/nozzle/container configurations in order toinsure isokinetic sampling.5.2 Thi 16、s practice is designed to be used by field personnelcollecting ...
A flow-rate proportional (isokinetic) sampling probe provided with two identical axial-flow thermal flow sensors whose outputs are used in a differential manner together with a sampling nozzle flow controller to extract a flow-rate proportioned sample of fluid passing thereby, wherein one flow ...
Cascade impactors are typically characterized based on the nozzle geometry, number of stages, flow rate capacity, and the range of effective cut-off diameters of the impaction stages. The basic principle of a cascade impactor is based on the jet impingement. It is mentioned that the operation ...
Additionally, the methods are used to ensure that the airflow particle inlet velocity to the sampling nozzle is the same as the duct velocity. The pressure was measured using the S-type pitot tube on four boiler levels at the full load capacity of the boiler. At 100% fuel-f...
