Keywords:
Single and double flow V-groove absorber, porous media, thermal performance, pressuredrop, flow channel depthAbstract
This paper concerns theoretical study to investigate the effect of mass flow rate, flow channel depth and collector length on the system thermal performance and pressure drop through the collector, on V-groove absorber at single and double flow mode. This study has been conducted by using a developed internet based mathematical simulation. It concludes that in V-groove absorbers types, the double flow mode is 4 - 5% more efficient than the single mode. On the other hand the use of porous media in double flow increases the air heater efficiency to be 7% more efficient than an air heater in single mode, and 2 - 3% more efficient in double flow mode without porous media. The analysis and the graphs obtained in this paper can be a helpful tool for a design engineer to construct economical and efficient solar air heaters with technical dimensions.
