This paper purpose is to analyze the bioconvection nanofluid flow which contains both nanoparticles and
gyrotactic microorganisms. We investigated a flow in a horizontal channel considering the model proposed by
Kuznestov and Nield (2013). In this sort of problems, this model is more convenient and physical in comparison
with other models. The least square method is utilized to solve the problem considering complicated boundary
conditions. In addition, the impact of different parameters is investigated exhaustively on the temperature distri-
bution profile, nanoparticle volume fraction and the density of motile microorganisms. It is found that such pa-
rameters can highly affect them particularly their stability. The effect of these parameters is much more
obvious in vicinity of the channel walls.
