Analysis of solar radiation repercussions on 3-D Darcy- Forchheimer nanofluid in Flat Plate Solar Collector(FPSC) with power-law Stretching

Research optimises in renewable energy areas like solar energy to overcome the universal energy crisis. FPSC are extensively used for the collection of low-temperature solar thermal energy. Research reveals porous material is the most affordable and decisive technique in improvising FPSC. A 3-D model depicts the problem more precisely. This work uses nanofluid to numerically simulate the solar radiation effect on the 3-D Darcy-Forchheimer model of FPSC. Nanofluid flow is considered along the power law of a stretching surface inside the solar collector with the impact of thermal source/sink, solar diffusion and magnetic induction. Mathematical equations are reformulated according to flow problems under different constraints. The resultant highly nonlinear coupled homogeneous PDEs are explicated using MAPLE software. Investigations are carried out on heat transfer characteristics using various non-dimensional parameters. A comparative analysis of linear and nonlinear stretching is done to analyse the problem more efficiently. This research is obliging in increasing the efficiency of solar collectors. Also, outcomes of this research can be used in many areas like preheating fluids in industries, space heating, household solar water system etc.
