Thermal performance Analysis Using V-Shaped Fins in Solar Absorber Plate
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
In the present work, it is aimed to improve the thermal performance of solar absorber plate by applying v-shaped fins on the collector surface. An experimental analysis has been done to investigate and compare the thermal performance of flat plate and plate with v-shaped fins (α=60°, 45°, 30°) in natural sunlight. The investigation is spread for mass flow rate ranging from 0.007kg/sec to 0.025kg/sec for fixed relative pitch of 15cm. The black coated aluminium absorber plate of area 1.4 m2 is placed in the mid position of duct covered with acrylic glass. After analysis comparison is made indicating that useful heat gain in v-shaped finned plate is more than the flat plate at the particular day and time. Various losses also accounted during the analysis. There was also noticeable improvement in thermal performance in v finned plates in comparison to flat plate.
