Numerically the nanofluid flow (NFF) over a spinning stretching/shrinking surface subject to the magnetic field is examined in the current study. The NF is prepared by the dispersion of aluminum alloys (Ti6Al4V) nanoparticles (NPs) in the base fluid (EG + water). Ti6Al4V-NPs have unique properties such as biologic compatibility, high durability, high boiling point (1604–1660 °C), and erosion resistance, making them more suitable for the automotive industry and other engineering purposes. The current study aims to address and provide remarkable insights into the aforementioned physical parameters. The modeled equations of NFF are transformed into nonlinear DEs (differential equations) independent of dimension, and they are computationally solved by using the widely used parametric continuation method (PCM). The numerical outcomes are compared to published results. The relative error with the published work is 0.00404 %, which ensure the accuracy of the results. The impact of physical fluid parameters on the fluid motion, thermal energy, and mass distribution profiles are studied. The values and ranges of these parameters have been considered based on the better convergence of the flow equations. It has been determined that the fluid velocity fall offs with the impact of magnetic field and rising numbers of Ti6Al4V NPs. The skin friction rises with variations in the aligned magnetic field and sheet stretching ratio factor. In addition, the radiation absorption factor increases the energy distribution rate.
