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

Abstract

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

Fractional order simulation for unsteady MHD nanofluid flow in porous medium with Soret and heat generation effects

“…When the radiation parameter is increased, the fluid temperature rises. Ahmad et al 17 state that double stratified radiative Oldroyd‐B nanofluid flow with heat source/sink and higher‐order chemical reaction is nonlinear mixed convective bidirectional dynamics. Ahmad et al 18 studied the significance of convective Nield's conditions on radiative Casson nanomaterial flow over a bidirectional stretching surface.…”

Parameter study of porosity effects on surface temperature for a porous block under wind, water source and thermal radiation

“…Solar reflectance greater than 95% requires a thickness of 160 m. Sweat wicking and drying are hindered. A major personal thermoregulation pathway, moisture management, in hot, humid, and sunny conditions, is essential to wick sweat away from skin and evaporate it quickly so that heat can be dissipated, and the body can cool safely [20][21][22][23][24][25][26][27][28][29][30].…”
