Furthermore, averaged heat flux densities through the cylinder head have been calculated, enabling a comparison with the thermodynamic loss analysis.
Comparison of Flux Densities. Tables 3 and 4 show the second vector norm of the error between the circumferential (x) and axial (y) flux densities of the different analytical models and the 2D FE model shown in Figure 3(a).

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.
From the figure, it can be seen that at large air gaps (e.g., where (air gap- length)/(polewidth) = 38), the fringing is so severe that the magnitudes of the flux densities far outside of the device are similar to that in the center of the device.
The assumed flux densities for 3C286 were converted from very large array total-intensity measurements provided by Perley (private communication) and are consistent with the Rudy et al.
Tested to SAE J1455, this digital output Hall effect speed sensor is self-adjusting over a wide range of magnetic flux densities, eliminating the need to optimize the sensor position within a small magnetic flux operating range.
The magnetic flux density of the electro-magnetic field was altered by varying the amount of the electric current from 0, 2, 4, 6, 8, to 10 A, values that correspond to the magnetic flux densities of 0, 0.75, 1.23, 1.56, 1.69, and 1.85 Tesla, respectively.
Line of modular infrared heating devices (SpotIR, LineIR, StripIR, PanelIR, ChambIR, Hi-TempIR, and SimulateIR) produce heat flux densities ( -3 watts/[in.sup.2] to over 900 watts/[in.sup.2]) and radiation geometries (from 0.25 in.
The flux densities in different parts of the machine (pole, yoke, mover, air-gap) have to be computed.
This predicted free-free contribution to the flux densities was determined from the H survey of Gaustad et al.
