Book Description
Several optical design tools have been developed at the National Renewable Energy Laboratory (NREL) during the past two years. These have been used extensively both in-house and by industry to analyze dish concentrator systems and to optimize performance of such designs. The first program, OPTDSH, models single-element dish concentrators. The second code, ODMF, allows multifacet dish arrays to be modeled. The accuracy of performance simulations by these programs has been established by comparing predicted results with measured on-sun data. ODMF evolved from NREL's High-Flux Solar Furnace (HFSF) design tool, SOLFUR, and in fact is a special case of SOLFUR in which the primary facet array is ''on sun.'' Consequently, confirmation of the accuracy of SOLFUR would verify the results from ODMF as well. Furthermore, because OPTDSH can be viewed as a single-facet case of ODMF, determination of the precision of SOLFUR/ODMF would also substantiate OPTDSH. Thus, the approach to verifying the correctness of all three codes was to compare flux patterns as predicted by SOLFUR with those actually measured at NREL's HFSF. Measured vs. calculated data have been compared on the basis of flux distribution (in terms of contour plots) and peak flux for both single-facet and multiple-facet cases. Agreement in measured vs. predicted peak flux values has been obtained within the uncertainty associated with the measurement/calibration process. Excellent agreement has also been demonstrated by comparing contour maps of measured vs. computed flux levels. 7 refs.

Book Description
Discover the latest techniques and applications for solar energy concentrators in this essential guide for academics, researchers, environmentalists, and professionals seeking to harness the power of solar energy while reducing environmental impact and costs. This book is centered on contemporary fundamental techniques for collecting solar radiation and the prospective applications that show how solar energy concentrators (SEC) can be used in a variety of systems and may provide significant economic and environmental benefits. Around the globe, there is a tremendous drive to investigate the viability of utilizing solar energy, particularly in regions with temperate zones. The usage of solar energy in many sectors has grown over the years. The ongoing quest for an alternate energy source in response to the apparent depletion of fossil resources is the driving factor behind this transition. Fossil fuels are far more widely used now than ever before despite their rising price. Although all forms of renewable energy are accessible, solar radiation is the most prevalent and easily accessible. Using solar energy for higher processing temperatures is difficult despite being the most common clean and affordable renewable energy source on the planet. For this, solar energy concentrators (SEC) are a promising technology that could be used to harness both heat and electricity for diversified industrial operations. SECs are devices that harvest solar radiation and direct it to a single point of concentration. This book presents the most up-to-date fundamental strategies for the collection of the sun’s radiation. Moreover, SEC technical summaries are also evaluated concerning ongoing international assignments. Prominent applications are also featured to show the reader the scope of the SEC’s applicability. The potential implementations demonstrate that CSE can be employed in a wide range of systems and may offer considerable economic and environmental advantages.
