摘要
This study aims to investigate the impact of volume fraction on entropy generation in a melting stretching/shrinking sheet scenario, considering both first and second-order velocity slips. The investigation focuses on the mixed convective flow of a nanofluid in a porous medium comprising nickel-zinc ferrite and SAE 20W-40 motor oil, which is characterized by Society of Automotive Engineer. Ferrites possess exceptional resistance properties, a crucial consideration in microwave applications. The solution to the derived nondimensional flow governing differential equations is computed using the spectral local linearization method combined with a local non-similarity technique. An assessment of the error is performed to verify the convergence of the numerical approach utilized. A comparison to existing results for specific cases highlights a strong agreement. Various flow-influencing parameters are considered to investigate entropy production, Bejan number, velocity, temperature, heat transport, and skin friction characteristics. The outcomes are presented in graphical form for different parameter values. After simulation, it is perceived that the melting parameter and Darcy number disrupt the entropy by 35.94 and 2.21%, respectively, and enhance the heat transport rate by 27.71 and 2.72%, respectively. This work can be utilized in designing innovative materials for electronics and textiles, in environmental processes like groundwater movement and pollutant dispersion, and in the biomedical field like hyperthermia treatments, tissue engineering, and regenerative medicine.
