Experimental Study On Thermal Performance Of MWCNT Water Based Nanofluid In FPC And EVTC Using Concentric Heat Exchanger Tank
Abstract
Solar energy is the best available form of renewable energy, it is environmental friendly, the energy source is renewable to sustain the growing energy demand. There are many challenges were arises when collection and storage of solar energy though it is available free for capturing. There are many ways of collecting the solar energy those are Flat Plate Collectors and Evacuated Tube Collectors are widely used. In the present study, the characteristics of MWCNT water based Nanofluid used as Heat Transfer Fluids(HTF). is used in Concentric type Heat Exchanger Tank. Sodium Dodecyl Sulfate (SDS) and TritonX100 were used as surfactant and dispersant with 1:1 wt%. with the usage of MWCNT Nanofluid with EVTC 5-6% more with FPC and same were increased by 4-5%and 7% when Distilled water was used as HTF with EVTC and FPC respectively. The maximum outlet temperature of water coming out from tank reached to 76.8ºC and 72.44ºC EVTC and FPC respectively for the Concentric tank used with MWCNT Nanofluid temperature were limited to 68.45ºC and 62.85ºC respectively for EVTC and FPC in the Conventional tank. Finally results obtained for the heat absorption rate of collectors showed 255.56Watts and 276.25Watts FPC and EVTC respectively. In conclusions results suggest that MWCNT Nanofluid can be used as the working fluids in concentric type Solar Water Heater Tank to absorb more heat from Solar radiation and to convert Solar Energy into Thermal efficiency.
