Radiative bioconvection nanofluid squeezing flow between rotating circular plates: Semi-numerical study with the DTM-Padé approach

Modern biomedical and tribological systems are increasingly deploying combinations of nanofluids bioconvecting microorganisms which enable improved control thermal management. Motivated by these developments, in this study, a new mathematical model is developed for the combined nanofluid bioconvection axisymmetric squeezing flow between rotating circular plates (an important configuration in, example, bioreactors lubrication systems). The Buongiorno two-component nanoscale deployed, swimming gyrotactic considered do not interact with nanoparticles. Thermal radiation also included, Rosseland diffusion flux approximation utilized. Appropriate similarity transformations implemented to transform nonlinear, coupled partial differential conservation equations mass, momentum, energy, nanoparticle species motile microorganism under suitable boundary conditions from cylindrical coordinate system into dimensionless nonlinear ordinary value problem. An efficient scheme known as method (DTM) Padé-approximations then applied solve emerging equations. impact different non-dimensional parameters i.e. Reynolds number, rotational Prandtl thermophoresis parameter, Brownian dynamics Schmidt number Péclet on velocity, temperature, concentration density distributions computed visualized graphically. torque effects both plates, lower upper plate, determined. From graphical results, it seen that momentum regime suppressed clearly disk approaches disk. This inhibits axial produces retardation. Similarly, enhancing tangential velocity distribution decreases. More rigorous therefore development leads deceleration. Tables provided multiple values parameters. numerical obtained DTM-Padé computation show very good agreement shooting quadrature. shown be precise stable semi-numerical methodology studying multi-physical problems. Radiative heat transfer has an influence transport characteristics. When neglected, results obtained. It include radiative models dual damper technologies since high temperatures associated can significantly enables more accurate prediction actual thermofluidic Corrosion surface degradation may mitigated designs.
