Comparative assessment of propylene glycol Molybdenum disulfide (MoS2) and silicon dioxide (SiO2) Prandtl-Eyring fluid experiencing non-uniform heat source, Navier slips and nonlinear thermal radiation

The development of hybrid nanofluids has aided the efficient operations of industrial equipment and the use-fulness of various nanotechnology processes. Using the nonlinear Rosseland approximation heat flux, this paper analyzes the transport features of an MHD Prandtl-Eyring hybridized nanofluid over a bidirectional rotating sheet subjected to a thermal and exponentially expanding space-based heat source. The developed mathematical model includes the hybridization of Molybdenum disulfide (MoS2) nanoparticles and Silicon dioxide (SiO2) nanoparticles in a propylene-glycol (C3H8O2) based orthodox fluid, as well as the impact of velocity slip and temperature jump wall conditions. To solve the underlying model equations, similarity transformations are employed to convert the initial partial derivatives into regular third-order derivatives, which are solved with the Chebyshev wavelet scheme. The numerical results correlate perfectly with the relevant literature under con-strained conditions. Several tables and graphs depict the impacts of the physical parameters on the quantities of interest in the current analysis. As the amount of thermal radiation, the Prandtl-Eyring material term, velocity slip and the thermal heat source increase, heat transmission is greatly enhanced. The hybridized propylene glycol-based nanofluid provides better heat propagation in the system than the unitary nanofluid. The velocity profiles accelerate due to increases in the rotation and Prandtl-Eyring terms, but decelerates due to the slip and magnetic fields terms. The skin frictional factor (Cfx) is found to be lower for the unitary nanofluid (SiO2- C3H8O2) with alterations in the values of the slip and Prandtl-Eyring parameters as compared to the hybridized nanofluid (MoS2-SiO2/C3H8O2).
