Abstract
Solar air heaters are the flat plate
collectors used for a variety of purposes to heat water and air respectively.
Comparing solar water heaters to solar air heaters, the former are often
smaller, less costly and simpler. Because of the sluggish rate of heat transfer
between the absorber plate and the air moving through the duct, it is common to
assume that a solar air heater has a low thermal efficiency. The heat transfer
rate needs to be increased in order to increase thermal efficiency, which will
make a solar air heater a more efficient solar energy utilization system. In
solar air heaters, artificial roughness significantly affects the friction
factor and heat transmission coefficient. Before conducting real experiments,
several scientists carried out a number of computer simulations to examine the
effects of different artificial roughness types, locations, and heights within
solar air heater ducts across a broad range of parameters. Real-world
applications can utilize optimal data provided by computational fluid dynamics
(CFD) analysis. In current work, the artificial roughened duct with
computational fluid dynamics approach employed by several researchers is
described.
