| 研究実績の概要 |
Problem (1), Single flag-type energy harvester:
Optimum shape design is being considered, based on a perturbation method-approach applied to Theodoresen's analytical fluid-load model. A fundamental, analytical stability study of a hanging flag in fluid flow is being developed as well.
Problem (2), A system of many interacting flag-type energy harvesters:
A computational model based on an articulated flag model and a discrete vortex flow model has been developed. (In principle, any number of flags is possible; the number is limited only by the computer memory.) The analysis module has been completed. An optimization module (for determining the optimum positions of the individual flags, for maximum power output) is under development.
