Experimental investigations of using silica aerogel to harvest unconcetrated sunlight in a solar thermal receiver
… flux reaching the earth’s surface. Current flat plate solar collectors have significant heat losses and achieving higher temperatures without using concentrating optics remains a challenge. In this work, we designed a prototype flat plate collector using silica- aerogel. Optically …

Simulation of a solar water heating system
… conducted on an experimental system, using a flat plate collector and solar storage tank, auxiliary to an electric geyser. Temperatures were recorded, solar radiation was measured using a solarimeter and thermosyphon mass flow rates were measured using a thermistor inserted into the flow …

Analysis and design of a cylindrical parabolic solar collector
A cylindrical-parabolic solar collector was thermally optimized for a winter season using a weather model and an extension of the present state-of-the-art collector theory. An accurate model for the cover transmittance and a seasonal performance model was developed. The optimum collector dimensions …

Availability of solar energy at Baghdad, Iraq and its application to absorption refrigeration for cold stores purposes
… energy available is collected by a three covers flat plate collector with selective coating applied to the absorber plate surface. The parameters influencing the best year round thermal performance of the solar collector are investigated. These parameters are mainly, the collector tilt and the …

Review of solar thermoelectric energy conversion and analysis of a two cover flat-plate solar collector
… of thermoelectric energy generation and solar collectors. Existing forms of flat plate collectors and solar concentrators were surveyed. A thermal analysis of a common two-cover flat plate solar collector was then performed. The model focused specifically on radiation absorption through the …

Flat-Plate Solar Collectors for Water Heating with Improved Heat Transfer for Application in Climatic Conditions of the Mediterranean Region
… is to improve the thermal performance of passive flat plate solar collectors using a novel cost effective enhanced heat transfer technique. The project work focuses on the process of energy conversion from the collector to the working fluid. This is accomplished by employing an aluminium grid …

Experimental investigation and mathematical modelling of dynamic equilibrium of novel thermo-fluids for renewable technology applications
… solar thermal systems where concentrated collectors are employed have been utilised for power generation, whereas low-temperature solar systems where non-concentrated collectors such as flat plate are employed have been used for heat generation. A review of the literature indicates that by …

Analytical methods for evaluating two-dimensional effects in flat-plate solar collectors
… experimental and theoretical predictions of flat-plate solar collector performance. There is a need to identify both those areas of analysis which need improvement as well as those which are already adequate. Two new methods of absorber-plate thermal analysis which can be used within the …

Low-Concentrating, Stationary Solar Thermal Collectors for Process Heat Generation
The annual gain of stationary solar thermal collectors can be increased by non-focusing reflectors. Such concentrators make use of diffuse irradiance. A collector’s incidence angle modifier for diffuse (diffuse-IAM) accounts for this utilization. The diffuse irra-diance varies over the collector …

Analysis of the Impact of Solar Thermal Water Heaters on the Electrical Distribution Load
… water heater model is developed for two types of collectors namely the flat plate and evacuated glass tube collector. Simulations are performed with the climate data from two cities - Madison, WI and Tampa, FL - which belong to two very different climate zones in the United States. …
