The directionality of the tidal flow throughout the tidal cycle has important implications for tidal energy capture with respect to turbine performance, capacity factor, and structural loading. There has been a tendency to infer that energetic sites possess near bi-directional flows or that...

An experimental study was carried out to develop a new type of two-way diffuser suitable for a fluid flow energy conversion system. It is known that the power available from the fluid flow is proportional to the cube of the free stream velocity of the flow. Therefore, in order to take higher...

Tidal energy could convert into power on the basis of height difference (Tidal Barrages) and on the basis of flow speed (Tidal Current). The studies have shown that tidal barrages have some disadvantages concerning the environmental impacts and the limits of availability of economic sites. Tidal...
