ABSTRACTThe current study investigates the weakly hydromagnetic and bioconvection nanofluid flow of Williamson fluid, which conveys gyrotactic microorganisms, over a three-dimensional Riga surface. The primary objective is to stabilize biological, mechanical, thermal systems through introduction exponentially decaying rheology in both momentum energy equations, known as electro-magneto-hydrodynamic actuator (EMHD). As such, working fluid assumed be dissipative, with significant consideration given magnetic Reynolds number higher-order reaction rate. To simplify phenomenon suspended nanoparticles' bioconvection, an appropriate similarity transformation applied, converting system partial differential equations (PDEs) into ordinary (ODEs). analyze governing parameters, numerical approach, Galerkin Weighted Residual Method (GWRM), employed. results are presented tables graphs, providing valuable insights. findings highlight that Hartmann improves weak movement thermophoresis positively affects all distributions. Moreover, temperature field influenced by Brownian motion, leading inflation, while concentration experiences decrease due lower particles available for reaction. Furthermore, higher buoyancy forces indicate movement, resulting reduction chemical rate.KEYWORDS: Gyrotactic microorganismsWilliamson fluidGalerkin methodNanoscienceEMHDRiga plate Nomenclature j0=current density [A/L2]M0=surface property [Wb/L2]μ=variable viscosity [kgL−1s−1]C=fluid [mol.]ρ=fluid [Kgm−3]ν=kinematic [L2/s]β4=material constant [-]β1=viscosity parameterNt=Thermophoresis [-]Sc=Schmidt [-]K=Williamson parameter [-]Gn=Gyrotatic Grashof [-]Ec=Local Eckert [-]λ=chemical [-]Tw=temperature [K]Cw=concentration [mol.L−3]C∞=free stream [mol.L−3]w=velocity component z− [Ls−1]u=velocity x− direction [LS−1]Kr=rate [S−1]ρf=density [Kg/L3]r0=diameter magnets [L]Do=mass diffusivity[L2/s]T=fluid [K]Cp=specific heat capacity [J/kg.K]Ha=modified Hartman [-]β2=thermal conductivity [WL−1K−1]Nb=Brownian motion [-]β5=stretching ratio [-]Pr=Prandtl [-]Gr=thermal [-]χ=bioconvection [-]Le=Lewis [-]Pe=Peclet [-]Nw=motile [mol.Kg−1]T∞=free [K]N∞=free Stream motile microorganisms [mol.Kg−1]v=velocity y− [LS−1]x,y,z=cartesian coordinate [L]AcknowledgmentsThe authors appreciates acknowledge reviewers their constructive comments.
