Improved thermal-vacuum compatible flat plate radiometric source for system-level testing of optical sensors
In this work, we describe an improved thermal-vacuum compatible flat plate radiometric source which has been developed and utilized for the characterization and calibration of remote optical sensors. This source is unique in that it can be used in situ, in both ambient and thermal-vacuum environments, allowing it to follow the sensor throughout its testing cycle. The performance of the original...
متن کاملAn experimental study of solar thermal vacuum membrane distillation desalination
An experimental desalination system coupling a vacuum membrane distillation (VMD) unit and a vacuum tube solar heat collection (SHC) unit was developed and tested. The parametric sensitivity of the VMD unit performance was investigated first using an electric heater as the heat source, and then the whole system was examined using solar heat. It was revealed that hot feed temperatures higher tha...
متن کاملinvestigation of absorber plate porosity effects on a solar air heater performance with slatted glass
in this research a flat plate solar air collector was investigated under direct solar radiation consisted of a slatted glass cover, perforated absorber aluminum sheets (porosity 0.0177, 0.0314 and absorber thickness of 2.5 mm). the effect of porosity on absorber efficiency of collector was evaluated. six levels of air mass flow rates (0.0056 to 0.0385 kg m-2 s-1) were adopted.average solar ener...
متن کاملefficient solar air heater with perforated absorber for crop drying
outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...
متن کاملSolar Thermal Collector System Modeling and Testing for Novel Solar
Solar cookers are aimed at reducing pollution and desertification in the developing world. However, they are often disregarded as they do not give users the ability to cook after daylight hours. The Wilson solar cooker is a solar cooker designed to address this problem by converting solar energy and storing that energy as heat in the form of molten salt (lithium nitrate). This thesis involved r...
