【 摘 要 】

The effects of thermal radiation and chemical reaction on the mixed bioconvection nanofluid flow with gyrotactic microorganisms along horizontal channel are analysed.The homotopy analysis method (HAM) is assigned to find the analytic solution of ordinary non-linear differential equations using appropriate similarity variables. The physicalinterpretation of the required solutions is exhibited through plots. It is observed thatthetemperature of the fluidincreases when rising the values of thermal radiation and thermophoresis parameter. Also the solute concentration and the mass transfer rate arehighly influenced by the chemical reaction parameter.
