Optimized Design of a Novel Hydraulic Propeller Turbine for Low Heads

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

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 ...

Design of a Photonic Bandgap Fiber with Optimized Parameters to Achieve Ultra-Low Confinement Loss

In this paper, a novel design of all-solid photonic bandgap fiber with ultra-low confinement loss is proposed. The confinement loss is reduced remarkably by managing the number of rods rings, up-doping level, pitch value, and rods diameters. Moreover, the designed PCF shows ultra-flattened dispersion in L- and U-band. Furthermore, a new design, based on introducing of an extra ring of air h...
