Heat transfer analysis in nanofluid-based flat plate solar collectors has been investigated and presented in this work. Cu-H₂O nanofluid in absorber tubes of the collector has been considered in the present analytical study. Natural convection flow in the pipe is studied as free convective flow through a vertical cylinder filled with Cu-H₂O nanofluid. The governing nondimensional ODEs along with their appropriate boundary conditions are solved analytically. The impacts of numerous physical parameters like heat, Grashof number and volume of fraction concerning nanofluid are analyzed. The range of heat parameters is considered 1 to 3, while the Grashof number has been varied from 10-20 and the nanofluid volume fraction is varied from 1% to 3% in the parametric study. From the present study, it is observed that heat transfer enhancement occurs with an increase in the parameters mentioned.
