Abstract
The total amount of existing solar energy on earth is more than the World's current and estimated energy requirements. The radiative heat from the sun is capable of producing electricity. This study deals with hydrogen energy storage by growing the heat transmission enactment of PTSC (Parabolic Trough Solar Collector) in the presence of thermic heat, resistive heat, buoyancy, magnetic field, and uneven heat sink/source. The Oldroyd-B and Maxwell fluids are the shear-thinning fluids with rheological differences. This study investigates the best heat transfer performer among these two, which helps to enhance the heat transfer in PTSC. A mathematical model was established and resolved numerically to examine this. The study outcomes are deliberated with the assistance of pictorial and numerical evaluations. Thermal radiation with Oldroyd-B fluid combination helps to enhance the heat transmission rate of PTSC to another level.
