The aspect ratio of the\ convection cell becomes large as Prandtl number becomes large. With respect to temporal change in\ bioconvection, the flow can be classified into three states (steady, unsteady, collapse). Comparing\ bioconvection to the bubble convection that is a kind of particle-driven convection, there is a similarity\ that steady and unsteady-state can be divided by Prandtl number, while the difference is observed in\ the presence of the collapse pattern.}, pages = {13--18}, title = {Numerical study of the aspect ratios of the bioconvection cell as a function of Prandtl and Rayleigh number}, volume = {67}, year = {2016} }
