Computational Study of Melting Effects on Hybrid Nanofluid Flow Over a Rotating Cylinder with Solar Energy Applications

This work is intended to scrutinize the hybrid nanofluid flow via a rotating cylinder. The significance of melting phenomenon with velocity slip is investigated. The thermal transportation phenomenon takes place in an atmosphere of combined convection, thermal radiation and heat source. Furthermore, the mass transportation is carried out in thse existence of activation energy. Free convection has an essential function in improving heat transfer in energy systems for example solar collectors and power plants, contributing to lower energy consumption and improved operational efficiency. Moreover, examining key parameters including magnetic field effects, thermal radiation, and nanoparticle geometry provides valuable insights for controlling fluid flow and optimizing heat transfer. Such advancements have practical significance in numerous industries, with power generation, aerospace, molten metal processing, nuclear energy systems, and aeronautical engineering. The PDEs governing the problem are changed into a system of ODEs that describe the physical state of the system. These ODEs are tackled numerically using MATLAB’s bvp4c method, and the resulting computational and graphical outputs are validated against results reported in earlier studies. Graphs show how important elements affect the fluid transport characteristics. The curvature parameter is amplified due to the velocity profile’s greater values. The thermal transportation is increased with larger thermal radiation. Elevated levels of the melting factor and velocity slip parameter exhibit a decline in relation to the Reynolds number.
