Unveiling the Triple Diffusion Bioconvective Applications for Couple Stress Nanofluid Due To an Oscillating Regime with Variable Thermal Features

Abstract

AbstractThermal engineering and industrial processes see various multidisciplinary applications due to the enhanced thermal performances of nanomaterials. The nanomaterials preserve a profound breakthrough in enhancing the heat transfer phenomenon. The objective of the current investigation is to address the thermal applications of couples-stress nanofluid in the presence of triple diffusion effects. The analysis is subject to the bioconvective significance of the suspension of microbes. The viscosity and thermal conductivity of a couple stress fluids are assumed to be variable. Moreover, we endorse linear thermal radiation effects and approach the problem with an effective Prandtl number. The source of flow is an oscillatory, porous stretching surface. Based on suggested flow assumptions, the model is represented via nonlinear couple partial differential equations (PDEs). We employ the homotopy analysis scheme to forecast the analytical simulations. The physical outcomes for the involved parameters are observed for the modeled problem. Various aspects based on the deduced results are claimed. Based on the performed analysis, it is observed that the magnitude of skin friction decreases due to variations in the couple-stress fluid parameter. The heat increases with the modified Dufour number and variable thermal conductivity coefficient. Furthermore, an increasing behavior of nanoparticle solutal concentration has been observed due to the Dufour-Lewis number.
