This research communicates the triple diffusion perspective of Eyring-Powell nano-materials configured by a periodically moving configuration. The thermal consequences of variable natures are utilized as a novelty. Combined magnetic and porous medium effects are also involved, which result in a magneto-porosity parameter. The thermophoretic and Brownian motion aspects are reported by using Buongiorno's nanofluid theory. The formulated flow equations in non-dimensional forms are tackled with the implementation of a homotopy analysis algorithm. A detailed physical investigation against derived parameters is presented graphically. Due to periodically accelerated surface, the oscillations in velocity and wall shear stress have been examined.

To respond to the demands of modern technological processes, the employment of nanofluids to maximize energy efficiency has been a topic of interest to many scientists. The stability of such nanofluids can be appropriately enhanced with the use of gyrotactic microorganisms. In the current framework, we inspect the triple-diffusive bioconvection flow of electro-magnetized Sutterby nanofluid via an oscillatory stretchable surface with Brownian diffusion of both nanoparticles and microorganisms, thermophoresis, buoyancy, and inertial forces. With the utilization of acceptable dimensionless variables, the governed flow equations are first metamorphosed into non-dimensional form, and solutions of the resulting equations are computed using the overlapping grid spectral collocation scheme. The rationale for choosing this numerical approach is provided by computing residual errors and condition numbers. The significance of physical parameters on the quantities of engineering interest and flow profiles is discussed. The main results include that reduced surface shear stress and minimal oscillatory nature of velocity are achieved with the inclusion of porous media, inertial forces, bioconvection, and nanofluid buoyancy forces. Temperature and rate of heat transfer are upsurged with the existence of variable thermal conductivity, nonlinear radiation, and convective heat conditions, which advocate that such features promote superior heat transport within the Sutterby working fluid. Growth in solutal Dufour Lewis number increases solutal concentration while reducing solutal-mass transfer rate. Improvement in microbial Brownian diffusion parameter causes enhancement in the rate of motile microorganisms transfer and reduction in the concentration of gyrotactic microorganisms. This implies that the random motion of motile microorganisms plays a prominent role in the dynamics of microorganisms.

This paper aims to investigate the transfer of heat phenomenon in a hydromagnetic time dependent flow of micropolar fluid across an oscillating stretchable curved surface by using the Cattaneo–Christov heat flux model, which considers thermal relaxation time. An elastic curved surface that stretches back and forth causes the flow situation. The flow equations are derived as nonlinear partial differential equations by incorporating a curvilinear coordinates system, which is then solved analytically via the homotopy analysis method (HAM). The accuracy of the derived analytical results is also examined by using a finite-difference technique known as the Keller box method, and it is found to be in strong agreement. The influences of various physical characteristics such as material parameter, magnetic parameter, thermal relaxation parameter, a dimensionless radius of curvature, Prandtl number and ratio of surface’s oscillating frequency to its stretching rate parameter on angular velocity, fluid velocity, pressure, temperature, heat transmission rate, and skin friction and couple stress coefficient are depicted in detail with the help of graphs and tables. Furthermore, for the verification and validation of the current results, a tabular comparison of the published data in the literature for the case of flat oscillating surface versus curved oscillating surface is carried out and found to be in good agreement.
