Wind energy is a primary component of contemporary renewable energy development. In this talk, the speaker will describe his efforts in the study of wind energy. Issues involved are wind turbine flow control, modeling of structural vibrations of turbine towers, offshore structures, etc. Computational method based on the Finite Volume Method (FVM) using OpenFOAM and FLUENT softwares is being developed. The speaker will show short animations of wind turbine flow motion obtained by these computational fluid dynamics softwares ANSYS/FLUENT and OpenFOAM.
