Increase of the graphitization degree and crystallite size of the HCNFs from normal coaxial nozzle may arise from the smoother flow of both core and shell polymer solutions, which were pulled out from the same comparative levels of nozzle-end configuration.
The model describes the process occurring in the absorber as the most important step in the WLFGD system by establishing what increase in SO2 removal can be achieved as the higher levels of nozzles come progressively into service when initially the first spray header is operating alone, and keeping the other operating conditions under control.
We have clarified the influence of the applied voltage on the coaxial electrospinning of the PMMA/PAN composite nanofibers with different levels of inner nozzle-end and studied the effect of the levels of inner nozzle-end on the morphologies and physical properties of the obtained HCNFs.
We studied how operational conditions (rotation speed, fill level, number of nozzles, and spray rate) influence the coating uniformity.
Laboratory tests showed that the spacing between nozzles could be too small, reducing the level of charge per nozzle.
Hollow carbon nanofibers (HCNFs) were prepared by electrospinning method with several coaxial nozzles, in which the level of the inner nozzle-end is adjustable.
In this study, we used the coaxial nozzles, in which the level of the inner nozzle-end can be adjustable to clarify the effect of the balance level of the inner and the outer nozzle-ends on the physical properties (e.g., morphology, specific surface area, crystallinity, and graphitization degree), which will also affect the electrical properties of the obtained HCNFs.
There were hair products by Chroma Studios including hairspray with a nozzle containing three levels of hold from soft to firm.
The overall sound pressure levels (OASPLs) of a short solid concial plug-nozzle (CPN) are found to be within 3 dB of those of the baseline noise levels of a minimum length contoured plug-nozzle operated at the same pressure ratio and having the same annular throat area.
Under certain conditions of nozzle spacing and flow parameters, the combined sound pressure level spectrum for the clustered nozzles displays a double peak.
The details of nozzle design depend strongly on application.
