Comparison of SWCNT + MWCNT and SWCNT + MWCNT + Fe3O4 nanofluid across a spinning disk with suspended joule heating and non-linear thermal radiation: Multi-linear optimization

Background: Fluid flow over an infinite impermeable rotating disk has profound applications in computer storage, lubrication, aerospace, chemical engineering, the geothermal industry, the food industry, the cooling of rotating machinery, gas turbines, thermal energy systems, etc. This motivated me to mathematically model the radiative magnetohydrodynamic Over an endlessly impermeable rotating disk, nanofluid flows. Appropriate similarity frameworks are utilized to solve the nonlinear PDEs. Methodology: Further, ODE45 (MATLAB) is used to analyze the transport of heat, mass, and flow. The distinction of this model is the mixture of nanoparticles in the fluid’s base. The flow is analyzed considering two cases. Case 1: (Formula presented.) and Case 2: (Formula presented.) Conclusion: A straightforward solution for the radial (Formula presented.) axial (Formula presented.) and azimuthal velocity (Formula presented.) heat and substance concentration (Formula presented.) is discovered, and its impact on fluid movement is studied with relation to several dimensionless characteristics. A good agreement is obtained in the present model with certain added features to the existing work. The primary finding of this research is the inclusion of SWCNT, and MWCNT has exhibited more comparing skin friction, the Nusselt number, and the Sherwood number SWCNT, MWCNT, and in the same carrier fluid. SWCNT and MWCNT In industrial procedures, nanoparticles are more effective for cooling purposes. Compared with SWCNT, MWCNT, and (Formula presented.).
