Analysis of entropy generation in the flow of MHD water–ethylene glycol nanofluid over a spinning down pointing vertical cone
Objectives: Entropy generation is investigated by considering the consequence of Magnetic field in H2O − C2H6O2 (50:50) mixture based Al2O3 and Fe3O4 nanoparticles. The 2D magnetohydrodynamic mixed convective boundary layer fluid flow characteristics are assumed to be independent of time at every po...

| description | Objectives: Entropy generation is investigated by considering the consequence of Magnetic field in H2O − C2H6O2 (50:50) mixture based Al2O3 and Fe3O4 nanoparticles. The 2D magnetohydrodynamic mixed convective boundary layer fluid flow characteristics are assumed to be independent of time at every point. The boundary conditions are mathematically formulated with the slip conditions (velocity and thermal). Significant outcomes: The investigation discloses that the F′(η) (tangential and swirl) drops for the increasing effects of the M. Fe3O4 shows a rise in velocity compared to Al2O3. In case of Magnetic parameter Fe3O4 shows 0.71% and 0.89% of Cf and Nu respectively compared to Al2O3. For changed estimation of the Brinkman number, both the Entropy generation and Bejan number shows opposite behavior. To verify the exactness of the numerical method, a comparison is made between the obtained outcomes and previously published results, corresponding to the skin friction and Nusselt number and the results are reliable. Practical implications: This work is developed to multiply the rate of energy transference and increasing the execution as well as effectiveness of energy delivering in industrial field. This model considers the effect of magnetic field, since it helps in achieving energy circulation in numerous devices like refrigerators and in other heating applications. Especially using the magnetized nanofluid helps in improved energy transmission in biomedical imaging. Additionally, the entropy generation model is verified using the thermodynamics second law. |
