ABSTRACT:
This report presents results from a parametric study of the Sandia Laboratories' second-generation 2-m, 90° parabolic-cylindrical solar collector design. A computer simulation was developed to provide cumulative all-day performance results or instantaneous solar noon results for three

annular solar receiver assemblies: 2.223-, 2.54-, and 3.175 cm-o.d. tubes with concentric glass jackets. Representative clear spring, summer, and winter conditions for Albuquerque, NM, were modeled. Design problems considered in the analysis included misalignment of the receiver assembly from the focal line, reflector trough tracking bias, variation in receiver tube operating temperature, and variation in the reflector trough one-dimensional slope errors and two-dimensional mirror errors. Changes in collector material properties and wind effects a real so summarized, and comparative performance results for evacuated versus nonevacuated annular receivers are given. Summarized performance results for all studies are provided graphically. For operating receiver-tube temperatures Show Less
