Hydromagnetic slip flow and heat transfer treatment of Maxwell fluid with hybrid nanostructure: low Prandtl numbers

Abstract

The present study investigates the hydromagnetic slip flow of Maxwell fluid with hybrid nanostructure through a porous rotating disk subject to low Prandtl numbers. The fluid medium is dissipative in nature. Fluid suction is implemented. Entropy generation analysis is carried out. The non-dimensional governing equations are solved using bvp4c in MATLAB. The impact of different embedded parameters on velocity and temperature profiles, and entropy generation number has been discussed and depicted in graphical and tabular forms. Specifically, the influence of low Prandtl numbers on fluid temperature and heat transfer rate of Maxwell fluid with hybrid nanostructure has been explored. It is envisaged that radial velocity peters out (controlled radial motion is attained) due to amplification of the magnetic parameter, Deborah number and slip parameter. Low Prandtl number gives rise to more heat transfer rate thereby imparting intensive cooling. Further, low Prandtl number yields low entropy generation thereby providing greater efficiency of the thermal system utilising Maxwell fluid with the Cu–Au hybrid nanostructure.
