Abstract
Energy application from sun to heat water is well known. Solar water heater is device which is used for heating the water for domestic and industrial purposes by utilizing the solar energy.In this review paper effect of porous material on the performance of solar water heater have been carried out.porous medium i .e metal foam, geometry of absorber plate and collector,other various things that have been investigate for performance improvement of the solar collector.Agitator is used in solar collector. The basic function of agitator in the riser tube is to increasing heat transfer; packing of collector surface with pebbles and metal chipsis for longer heat absorption and enhanced heat capture respectively. It has been found that the efficiency of the solar collector with porous medium is more among all other combinations. An ASHRAE standard is used to examine the effects of metal chips on the solar collector performance at different flow rates.
