In the Settings windows for Variable, write the expression for
radiation intensity (Irz), according to (3) and (4).
The increase in solar collector exit temperature follows a pattern resembling that of the solar
radiation intensity.
The third part is to apply this optimization model to determine the suitable double-layer thickness (lead-iron) for attenuating
radiation intensity of 0.1mSv/hr via the contour-plotting analytical technique.
Another method, known as spherical harmonic method, consists in a Legendre expansion of the
radiation intensity and the phase function in the radiation transfer equation [4-6].
The
radiation intensity of the experiment was 5kW [m.sup.-2].
In general, it should be observed that the highest intensity of radiation includes UV range of 200-380 nm and VIS range of 380-780 nm, whereas the part of NIR range of 780-1100 nm is characterized by low
radiation intensity. In Figures 5-7, the calculated mean spectrum distribution is depicted separately for the UV, VIS, and NIR range, respectively, for selected voltage value of arc generation.
CSP offers a number of advantages over conventional photovoltaic power generation: less fluctuation in power output relative to fluctuations in solar
radiation intensity, and stable power supply even under cloudy or nighttime conditions as the thermal energy, collected when available, can be stored.
This is equivalent to the UV-B
radiation intensity that would result from a 20% decrease in stratospheric ozone concentration and UV-B was enhanced by 40% at Xi'an during a clear day on the summer solstice.
