摘要

The aim of the contemporary investigation lies in supporting the heat transfer characteristics of Sutterby nanofluid influenced by gyrotactic swimming induced by the Riga plate. The attributes of nonlinear radiative heat transfer and excitation energy are integrated to explore the thermal potential. The equations of the governing flow problem are transmuted into a nonlinear ODEs by consuming a suitable transitions. The transformed problems are analytically computed by adopting the homotopy analysis method. The influence of some acquired factors upon velocity, thermal, nanofluid concentration, microorganisms distributions, coefficient of skin friction, local Nusselt, local Sherwood and motile density microorganisms numbers are scrutinized via graphs for pseudoplastic and dilatant nanofluid cases. The velocity distribution increases with a larger Deborah number and it declines for a higher measure of injection/suction factor for both fluid scenarios. The nanofluid temperature enhances for the greater measurements of the radiation factor. The modified Hartmann number and mass relaxation time parameter leads to downfall in the nanofluid concentration. The microorganisms profile diminishes as the Lewis number and the modified Hartmann number increase. The heat transmission rate improves when raising the values of the heat thermal relaxation parameter. The nanofluid concentration difference parameter leads to augmenting the entropy generation and Bejan number profiles.
