In this paper, an experimental and numerical analysis was performed on both carbon black nanofluids a biodegradable fluid in novel pump-free direct absorption solar collector (DASC). the experiments, nanofluid consisted of nanoparticles water with concentrations ranging from 0.005 to 0.020 wt%, while coffee colloid. The overall findings indicated concurrence: exhibited best thermal performance when compared pure water. optimum nanoparticle concentration 0.010 wt% yielded 102% enhancement base fluid. Furthermore, using computational dynamics (CFD) software study rig. According these simulations, optimal showed 76.6 - 90.9% increase fluids did not show significant which differs what has been reported scientific literature. Nevertheless, computer also slightly outperformed case used.
