The performance benefits of deploying tidal turbines in close side-by-side proximity to exploit constructive interference effects are demonstrated experimentally using two 1.2 m diameter turbines. arrayed at 1/4 tip-to-tip spacing, and their compared with that a single rotor. Tests were completed the 25 diameter, 2 deep wave current FloWave Ocean Energy Research facility. A detailed assessment ...

in this research, the steady-state flow filed around a 3d body and rotor configuration of the robin helicopter is simulated. the rotor is modeled by an actuator disk. for this purpose, an annular computational domain replaces the rotor and some modeled source terms are added to the momentum equations. this modeling of rotor considerably speed up computational time. the flow field over this heli...

in this research work with the aid of tagouchi experimental design and rawing of interaction curves with minitab software, the best rotor speed and dump temperature of mixing for physico-mechanical and rheological properties of the rubber compound with three mixing steps was obtained. moreover by plotting the mean curves in excel worksheet, the dependency of properties on rotor speed, dump temp...

Combined variable rotor speed and active blade twist helicopter technologies have the potential to reduce environmental acoustic impact of modern rotorcraft. This paper explores aeroacoustics, ground noise combined rotors, optimized for simultaneous mitigation source NOx emissions. An integrated approach is employed including free-wake aeroelastic modeling time-domain aeroacoustic formulations ...

The paper shows the implementation of simulation models an electromechanical energy converter on example induction motor with a squirrel-cage rotor in SciLab environment and its graphic library Xcos for building structural diagrams. Despite existence programs such as Simulink ANSYS Twin Builder, is completely free, which advantage use academic scientific research. being free significantly diffe...
