The effect of Schmidt number on the flow patterns is focused in this study. To perform stable computation even at high Schmidt number, third order upwind scheme is used to approximate the nonlinear terms of the density equation. The calculation shows that there is a tendency for the aspect ratio of the convection cell to become smaller with increase in Schmidt number. Since small aspect ratio is observed in experiments, this result suggests that the effective Schmidt number is larger than the usually used value in the simulation of bioconvection.}, pages = {1--8}, title = {The Effect of Schmidt Number on the Flow Patterns in Density Instability Model of Bioconvection}, volume = {69}, year = {2019} }
