Analyzing the interaction of hybrid base liquid C2H6O2–H2O with hybrid nano-material Ag–MoS2 for unsteady rotational flow referred to an elongated surface using modified Buongiorno’s model: FEM simulation

Abstract

Numeric simulations are performed for comparative study of MHD rotational flow of hybrid nanofluids (MoS2–Ag/ethylene glycol–water (50%–50%)) and nanofluids (Ag/ethylene glycol–water (50%–50%)) over a horizontally elongated plane sheet. The principal objective is concerned with the enhancement of thermal transportation. The three dimensional formulation governing the conservation of momentum, mass, energy, and concentration is transmuted into two-dimensional partial differentiation by employing similarity transforms. The resulting set of equations (PDEs) is then solved by variational finite element procedure coded in Matlab script. The intensive computational run is carried out for suitable ranges of the particular quantities of influence. Both the primary and secondary velocities and temperature are greater in values for the hybrid phase than that of nano phase but nanoparticle concentration is smaller for the hybrid phase. The increased values of parameters for thermophoresis, Brownian motion, shape factor, and volume fraction of ϕ2 made significant improvement in temperature of the two phases of nano liquids. Results are also computed for the coefficients of skin friction (x, y-directions), Nusselt number, and Sherwood number. The present findings manifest reasonable comparison to their existing counterparts.
