Experimental Investigation on Efficiency of Flat Plate Solar Collector with BN/H2O Nanofluid

Solar Water Heating is an effective method of utilizing solar heat to perform many useful tasks. The energy from the sun can provide hot water for many applications, displacing the ssneed to burn fossil fuels. A solar collector is the main component for absorbing heat from solar beam and utilizing it for heating purposes. One way to absorb more heat from the solar beam is to modify heat characteristics of the working fluid. With the development of nanotechnology, an innovative heat transfer fluid arises. Nanofluids, a relatively new class of fluids which consist of a base fluid with nano-sized particles (1-100 nm) suspended within them. These particles are generally metals or metal oxides. Nanofluids have been considered as a new-type heat transfer fluid because of their substantial increase in liquid thermal conductivity, liquid viscosity, and heat transfer coefficient. Solar water heating is an effective method for heat demands in domestic applications. Solar collector is a main component of any solar water heating system. In this proposed work, the effect of BN–water nanofluid, as the working fluid (absorbing medium), on the performance and the efficiency of a flat-plate solar collector is to be investigated experimentally.
