The flow-field around the rotor blades of an FOWT may be significantly influenced by six rigid-body motions floating platform via blade–wake interaction. Therefore, accurate prediction unsteady aerodynamic load which is calculated many conventional numerical approaches still questionable for FOWT. In this study, periodic pitching motion rotating turbine due to considered investigate effects vortex–wake–blade interaction performance computational fluid dynamics (CFD) simulations based on...

Current wireless power transfer (WPT) systems have limited charging distance and high induced electromagnetic field (EMF) leakage. Thus, we first proposed a thin printed circuit board (PCB) type hybrid metamaterial slab (HMS) combining two kinds of cell structures. The cells in the center area HMS zero relative permeability straighten magnetic direction. located at edges negative change outgoing fields to opposite direction by boundary condition. Therefore, can be more confined between...

This study analyzed and validated a 1 MW hydropower turbine system using computational fluid dynamics (CFD) in conjunction with field test data. The domain of the includes runner blade, vane, duct, both inflow outflow free surface flows. An implicit unsteady flow solver SST k-ω turbulence model were employed. rotational motion rotor blade was simulated moving reference frame (MRF) method. To handle non-conformal mesh among intake, runner, outlet domains, an internal interface boundary...
