Description
Summary:This work introduces experimental results of an Al^sub 2^O^sub 3^ -water based nanofluid as the working fluid for flat tube in plate type solar collector. Experimental test setup comprises a solar collector, closed working fluid system and measurement devices (flow meter, thermocouples, temperature meter and digital solar power meter). The Base case was experimented with di-ionized water with a flow rate of 1 lpm. In second case, Al^sub 2^O^sub 3^ nanoparticles are mixed in di-ionized water to get nanofluid of 0.5% volume fraction concentration. The maximum difference between outlet and inlet temperatures of the solar collector was 14.4° C with the solar irradiance of about 788 W/m^sup 2^ while in case of water the maximum temperatures difference was 10.7° C with a solar irradiance of about 781 W/m^sup 2^.
