Environmental Engineering Science, W. M. Keck Laboratories, California Institute of Technology, Pasadena, CA 91125 The design and testing of a solar-powered fiber-optic cable reactor prototype for the photocatalytic destruction of organic pollutants is presented. A concentrating collector directs sunlight into a fiber-optic cable which transmits light to a Ti02 photocatalyst immobilized on the ...
nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...
Abstract Passive building strategies in tropical climates are believed to create thermal comfort, thereby enhancing the productivity of workforce office buildings. Very little study, however, exists on impact these passive design workers This study presents results workers, taking samples from buildings Lagos, Nigeria. Copies questionnaires were administered gather required data. Observation gu...
Incompressible magnetohydrodynamics is often assumed to describe solar wind turbulence. We use extended self-similarity to reveal scaling in the structure functions of density fluctuations in the solar wind. The obtained scaling is then compared with that found in the inertial range of quantities identified as passive scalars in other turbulent systems. We find that these are not coincident. Th...
Currently, passive robots are designed following a trial and error process in which the existence of a stable walking cycle for a given passive robot’s model is analyzed using Poincaré maps. The standard stability analysis procedure suffers from discretization aliasing, and it is not able to deal with complex passive models. In this paper a methodology that allows finding conditions on the robo...
High temperature is the primary challenge in development of solar photovoltaic (PV) systems an arid climate. A rise diminishes performance PV and shortens their lifespan. The goal this manuscript to develop analytical model predict panels under a passive cooling system for environment. Taking into consideration link between panel its conversion efficiency, Kirchhoff’s Ohm’s laws complex circuit...
Introduction: The Genesis mission collected solar wind for 27 months at Earth-Sun L1 on both passive and active collectors carried inside of a Science Canister, which was cleaned and assembled in an ISO Class 4 cleanroom prior to launch. The primary passive collectors, 271 individual hexagons and 30 half-hexagons of semiconductor materials, are described in [1]. Since the hard landing reduced t...
Abstract In this study, a passive solar house prototype was built using Trombe wall and tested in the semi-arid region of Batna, eastern Algeria. Traditional local materials (stone adobe) were used for construction thermal storage wall. A new bio-based material made from date palm trunks insulation prototype. For better understanding heating comparative numerical simulation, Fluent, carried out...
