Abstract :

Researchers have significantly explored the fluid motion over rotating surfaces for their significant uses in many technical and manufacturing processes, including centrifugal compressors, gas and steam turbines, viscometers, centrifugal pumps, fans, spin‐coating, and computer storage systems. A low‐oscillating magnetic field plays a crucial role in heat transport efficiency, nanoparticle manipulation, and the enhancement of fluid stability and rheology. In view of this, the present study explores the consequence of a low‐oscillating magnetic field on the three‐dimensional unsteady stream of a nanofluid past a slowly revolving disk with quadratic thermal radiation, variable thermal conductivity, suction, and activation energy. The generalized Fouriers and Ficks law is also considered to analyze the mass and heat transport. The governing partial differential equations are transformed into dimensionless ordinary differential equations with suitable similarity variables. The finite difference technique is utilized to solve the resulting ordinary differential equations (ODEs) numerically. The impact of various factors on the concentration, velocity, and temperature profiles is shown visually. For the unsteadiness parameter, the skin friction increases by approximately 5.29%. As the suction parameter values rise, the velocity profiles decreases. The thermal profile increases with a rise in the temperature conductivity parameter's value. The rise in values of the radiation parameter intensifies the temperature profile. The concentration profile reduces as the concentration relaxation time parameter increases.
