Optimization of hydraulic turbine diffuser

A Multi-Element Diffuser Augmented Wind Turbine

A new class of diffuser augmented wind turbines (DAWTs) is presented. The new diffuser concept exploits aero-dynamic principles for the creation of high-lift airfoil configurations known from the aircraft industry. Combining this with our objective of obtaining a compact power-efficient design has enabled creation of a family of DAWT designs with energy capture potentials which exceed the power...

CFD Driven Optimization of Hydraulic Turbine Draft Tubes using Surrogate Models

Draft tube designs have to a large extend been based on intuition and on the experience of the design engineer. In a close future, CFD simulations coupled with optimisation algorithms will assist in the search for an optimal technical solution. Such a shape optimisation technique to redesign an existing draft tube is presented in this paper. By this method, a design can be predicted in terms of...

Numerical optimization of hydrofoil geometry for a Darrieus hydraulic turbine using dynamic mesh and central composite design

In this study, a Darrieus hydraulic turbine for power generation applications is chosen and the response surface methodology (RSM) based on central composite design (CCD) is applied to obtain the optimized design for its hydrofoil geometry to increase the torque coefficient. For this aim, all turbine performance factors, except hydrofoil geometry, were considered to be constant and the turbine ...
