This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The natural convection heat transfer relations for the heat transfer between absorber and cover plates of solar collectors have been studied. Interferometric techniques were employed to evaluate the local coefficients. Average values were obtained by integration of the local values. The results are presented in terms of correlations between Nusselt number and Grashof number. The investigations were carried out over tilt angles of 45 to 90 degrees. The Grashof number range tested was representative of that existing in flat plate collectors. The various geometrics included large flat enclosures, small aspect ratio enclosures representative of honeycomb or slat collectors, vee-corrugated (vee-grooved) collectors, and compound parabolic concentrators.

Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation into the convective heat losses in large aspect ratio flat-plate solar collectors are described. An experimental study has been undertaken on a specially designed test cell using a 3 inch Mach-Zehnder interferometer. Air at atmospheric pressure was used as the heat-transfer fluid. The experimental results include interferograms which show the thermal boundary layer formations and the temperature profiles. Local temperature profiles have been analyzed through the use of an optical comparator to determine local Nusselt number profiles, which have, in turn, been integrated to give average heat-transfer results. Angles of inclination from the horizontal of 45, 60, 75 and 90 degrees have been investigated. Aspect ratios from 9 to 36 were examined over a Rayleigh number range of 4,000 to 310,000. Finally, heat-transfer correlations have been developed for the prediction of local Nusselt numbers in the starting and departure corners and for the average heat-transfer results as a function of collector tilt angle.

This book was released on 1975 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements to flat plate solar collectors for heating and cooling of buildings are being evaluated by three parallel studies. The first study has demonstrated that suppression of convective heat transfer by honeycomb panels is possible even when the panel is inclined from the horizontal. The second study has resulted in a precise, simple equation for the free convective heat transfer through an inclined air layer. The third study has theoretically demonstrated that if an inner cover is V-corrugated, its solar transmittance may be enhanced.
