| Outline of Final Research Achievements |
Numerical simulations were carried out modeling the bioconvection generated by chemotactic bacteria in microgravity environments with gravity modulation, and the transport characteristics were examined. When the gravity modulation acts on the steady suspension of bacterial cells, the bioconvection occurs, and the three-dimensional plumes and bioconvection pattern are generated. The increase of interference between the plumes enhances transport characteristics. These results don't clarify in the previous results.
