Diffuser technology placed around hydrokinetic rotors may improve the conversion of fluid’s kinetic energy into shaft power. However, rotor blades are susceptible to phenomenon cavitation, which can impact overall power efficiency. This paper presents development a new optimization model applied shrouded by diffuser. The proposed geometry takes account effect cavitation inception. main contribu...

The tensile strength of water increases when solid particles are filtered out, and it becomes greater the smaller the remaining particles are. Natural particles are of random shape, making parametric studies on the relationship between tensile strength and particle characteristics difficult. In this investigation, using degased tap water from which natural particles larger than about 1 (m were ...
