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...
The objective of this study is to illustrate the unsteady aerodynamic effects a floating offshore wind turbine experiencing prescribed pitching motion supporting platform as sine function. three-dimensional, Reynolds Averaged Navier-Stokes equations with shear-stress transport (SST) k-ω turbulence model were applied. Moreover, an overset grid approach was used rigid body blade. current simulation results are compared various approaches from previous studies. loads blade demonstrated change...
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...
The recent increase in the use of permanent magnet rotor motors underlines importance designing a with an interior (IPM) structure, high power, and efficiency. This study analyzed shapes IPM for electric vehicles. Five types motor rotors automobiles were analyzed, including two hybrid In order to minimize number variables analysis, size stators was fixed only modified compare torque, torque ripple, efficiency back-electromotive voltage. When properties compared as function shape, shape...
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...
The accurate prediction of unsteady aerodynamic performance and loads, for floating offshore wind turbines (FOWTs), is still questionable because several conventional methods widely used this purpose are applied in ways that violate the theoretical assumptions their original formulation. major objective present study to investigate effects rotating blade due periodic surge motions an FOWT. This work was conducted using numerical approaches, particularly computational fluid dynamics (CFD)...
The inhibition of aflatoxin B1 (AFB1) metabolism by a water extract the root Scutellaria baicalensis and its flavonoids was examined in liver microsomes. AFB1 is known to be metabolized M1 (AFM1), Q1 (AFQ1), AFB1-8,9-epoxide (AFBO). potently inhibited production AFM1 cytochrome P450 (CYP)1A1/2 slightly reduced AFBO formation CYP1A1/2, CYP2B1, CYP2C11 CYP3A1/2 TCDD-treated rat IC50 values for were 6.8 122.4 μg/ml, respectively. Wogonin showed highest inhibitory activity towards among isolated...
Nonlinear aeroelastic computations are presented for a sweptback wing with underpylon/finned-store in the transonic and supersonic flow regions, where strong shock wave interactions exist. A modal-based coupled nonlinear analysis system matched-point concept has been developed using high-speed parallel processing technique.
