Impact of nonlinear thermal radiation for magnetized dissipative flow of ternary hybrid nanomaterial (Al2 O3- SiO2- Fe3 O4- H2 O)

Abstract

Present attempt explores convective flow of ternary hybrid nanomaterial by a porous space. Convective condition is imposed. Thermal expression is discussed through non-linear radiation, magnetohydrodynamics, heat source and dissipation. Entropy generation rate is calculated. Non-dimensional ordinary expressions are obtained by employing adequate transformation. Convergent series solutions are obtained by employing Optimal homotopy analysis method (OHAM). Variation of velocity, entropy rate and temperature via influential variable for ternary $\left(F{e}_3{O}_4+\text{Si}{O}_2+A{l}_2{O}_3/H_{2}O\right)$ are graphically examined. Larger magnetic field rises temperature and entropy rate where reverse impact observed regarding velocity. Decay in velocity occurs for suction variable. Entropy rate and thermal field against radiation have same behavior. An increment of thermal field is found for heat generation. Comparison of velocity for base liquid $\left(H_{2}O\right)$, nanoliquid $\left(\text{Si}{O}_2/H_{2}O\right)$, hybrid nanoliquid $\left(F{e}_3{O}_4+\text{Si}{O}_2/H_{2}O\right)$ and ternary hybrid nanoliquid is made. Increasing values of Brinkman number yield to augment entropy rate. Higher magnetic field intensify entropy rate and temperature while decreasing trend holds for liquid motion.
