Abstract: A fluid turbine apparatus for use with a turbine comprising a convergent section, a fluid turbine section adjacent to an outlet of the convergent section, and a divergent section adjacent to the fluid turbine section. The fluid enters through the convergent section and exits through the divergent section. The convergent and divergent sections are constructed using a modular grid-like structure supporting retractable wall panels. The internal vacuum created by the diffuser and the wind shear stresses on the convergent and divergent sections can be limited. Configurations of the convergent and divergent sections can be adjusted to suit prevailing wind velocities. Barriers of rotating deflectors are used to increase the effective area of the convergent and divergent sections during low wind conditions. Horizontally mounted aerodynamic deflectors may be used to decrease wind shear and drag on the divergent section, the turbine section, and on side walls of the convergent section.
