The paper describes the detailed techno-commercial analysis done on a 46 m2 solar air heating system developed in a food processing industry. The solar air heating system was connected to an indoor drier through a duct. A detailed performance analysis was undertaken on the system by loading with 75 kg of ripe mango flake. The product loaded was uniform in size having a thickness of 4mm. On a cl...

This study aims to improve the productivity of traditional multi-slope solar stills, which are still employed in isolated villages with no power and clean drinking water. The conventional was equipped a photovoltaic array system that heated water through an electric heater submerged basin increase stills. analyzed compared PV-coupled (PVSS) area 0.64 m2 (CSS). results showed PVSS improved more ...

Up to now solar heat has been stored mostly in well insulated water tanks. The volume of these tanks is as large as 3 m3 for relatively high solar fractions and up to 70 m3 for full solar coverage for a single-family house. Storage tanks of this size are expensive and space consuming. In new buildings, provisions can be made to accommodate large storage volumes but this type of system is not li...

A simple effect one stage ammonia-water absorption cooling system fueled by solar energy is analyzed. The considered system is composed by a parabolic trough collector concentrating solar energy into a tubular receiver for heating water. This is stored in a fully mixed thermal storage tank and used in the vapor generator of the absorption cooling system. Time dependent cooling load is considere...

We study the heating of charged test particles in three-dimensional numerical simulations of weakly compressible magnetohydrodynamic (MHD) turbulence (“Alfvénic turbulence”); these results are relevant to particle heating and acceleration in the solar wind, solar flares, accretion disks onto black holes, and other astrophysics and heliospheric environments. The physics of particle heating depen...
