Parametric Study of Parabolic Trough Solar Collector System: A Review
Abstract: The detailed thermal analysis of a parabolic trough collector (PTC) was carried out to predict the thermal performance. The analysis is based on the established theory of PTC—the radiation absorption, heat loss from the collector, and temperature distribution on the plate. An analytical program, suitable for use on a digital computer is developed for the purpose of studying the hourly behavior of a solar collector. The exergy output is optimized …

RADAR IMAGING THEORIES AND PRINCIPLES OF OCEAN WAVES CAPILLARY WAVES AND TYPES OF RADAR
Abstract: Capillary waves caused by the wind were measured in a wave tank. The capillary waves' height, slope, and frequency composition were all measured. The wave heights (from trough to crest) were found to be between 0.06 and 8.8 mm for winds between 2.2 and 7.6 m/sec. Wind speed affects the distribution of frequencies (wavelengths), with more high frequency waves occurring at faster wind speeds. An S-shaped curve with the sharply …
