Nonlinear Mixed Convective Bidirectional Dynamics of Double Stratified Radiative Oldroyd-B Nanofluid Flow with Heat Source/Sink and Higher-Order Chemical Reaction

Little is known in the literature about concept of nonuniform heat source/sink and higher-order chemical reaction for dynamics Oldroyd-B nanoparticles. Therefore, present article addresses features nonlinear mixed convection bidirectional MHD nanoparticles with thermal radiation aspects through porous space. Stratification effects both temperature concentration setups are also used mathematical model significance random movement thermodiffusion Shape-preserving transformations have been employed to convert transport equations into solvable forms. An innovative analytical tactic, namely, homotopy analysis method, has adopted find solution modeled problem. Behaviors pertinent parameters on profiles discussed various graphs. Inspection heat/mass against appropriate varieties made explained physically. Thermal profile augmented higher estimations space temperature-dependent links. Concentration diminished augmentation parameter. Sherwood number improved estimation 0 ≤ β t 100 reduced growth id="M2"> c . Nusselt declined upgraded amounts id="M3"> N b 3 id="M4"> 5
