CFD analysis of 2-dimensional artificially roughened solar air heater duct with additional circular vortex generator, inserted in inlet section is carried out. Circular transverse ribs on the absorber plate are placed as usual. The analysis is done to investigate the effect of inserting additional vortex generator on the heat transfer and flow friction characteristics inside the solar air heate...

use of fossil energy provides greenhouse gases emissions and therefore global warming phenomenon and the incidence of further consequences such as expanding deserts and blasting the dust storms in the middel east, including iran. taking advantage of renewable energy is the most appropriate solution to prevent greenhouse gas emissions. ahvaz region in the southwest of with a population of 133812...

This study is concerned with the results of a Life Cycle Assessment comparison between photovoltaic e silicon based modules and thin film modules e and solar thermal systems, as technologies which are usually installed for partially covering household energy demand. Several studies focused on energy and environmental performances of photovoltaic and solar thermal collectors, however they have b...

Thermo-hydraulic performance of a Double Pass Parallel Flow Solar Air Heater (DPPFSAH) roughened with perforated multi-V ribs has been studied experimentally in prior study and the effect variation open area ratio change relative roughness width analysed reported. The current work builds upon aforementioned earlier by discussing detail methodology various steps involved development correlation ...

Due to the depletion of fossil fuel reserves, it is now more important than ever explore and use alternate forms energy. “Solar energy a promising long-term solution that can meet world's needs. essential we energy-related solutions as soon possible. Solar solution. Artificially roughened solar air heaters perform better smooth ones under same operating conditions. However, artificial roughness...
