flux density

1. (spectral flux density or, strictly, spectral power flux density) Symbol: S . A measure of the strength of the signal received from a discrete source of emission. The dimensions of flux density are energy per unit time per unit bandwidth per unit area. The unit is the jansky.

Except the squish gap inlet 1 curve, the maximum heat flux densities appear at a crank angle range between 15 [degrees] and 20 [degrees].
However, the transformation introduces a deformation of the PM, causing errors in the calculation of the flux densities which, in turn, lead to a major error in the calculation of cogging torque and the torque ripple [13].
Also, the maximum and average airgap flux densities obtained from the FEM and sizing analysis agree well.
Figures 3-7 show the extrudate swell ratio (B) for various thermoplastic melts; namely, PS, ABS, PC, LLDPE, and PVC, respectively, as a function of the wall shear rate and magnetic flux densities (ranging from 0 to 51 mT) using two different die temperatures.
The significance of demonstrating that these very high solar flux densities can be attained at considerable power levels is that they make new process conditions, and therefore new industrial applications for solar energy, possible," said Meir Carasso, who manages the advanced industrial applications program at SERI.
Customers have been waiting for flux densities >10W/cm2 to replace expensive, power-hungry and toxic Mercury lamps in a range of high speed ink printing and adhesive curing applications.
In this stream, flux densities corresponding to the two low order modes [EH.
The general results suggest that the overall extrudate swell for all shear rates increased with increasing magnetic flux density to a maximum value and then started to gradually decrease at higher magnetic flux densities.
Three critical sections, which are shown in Figure 4 as numbers 3 through 5, were chosen and their corresponding flux densities were compared to the saturation level of the material from which the section is made.
With the highest flux densities available today equating to 2300 mW/cm2, these products expand the use of LEDs in wide-ranging applications for adhesive and paint curing, sterilization, skin treatment, forensics particle detection, currency verification, fluorescence and blacklight blue.
When another point in space is taken, because the weights of external and meta-atom flux densities change, these two frequencies at which the maximum enhancement and reduction happen also change, although they are still below and above the resonance frequency respectively.
The heat flux densities crossing the polymer mold interfaces, the mold surface temperature and the recorded pressure (considered as constant in the thickness-Fig.
