Energy and material saving
considerations, as well as economic
motivation have led towards developing an
energy efficient solar air heater. in order to
enhance the performance of the air heater,
different turbulence generators such as ribs,
baffles and delta winglets have been
proposed. in this project work, a pin-fin
based flat plate solar heater has been
developed and compared its performance
under two different configurations
(configuration 1- without pin-fins and
configuration 2 with pin-fins). the
performance of the solar air heater has been
evaluated under different climatic conditions
of coimbatore city in india with different air
mass flow rates. based on the performance
comparisons, the air flow rate through the
solar air heater is optimized.
