Effect of the number of blades and solidity on the performance of a vertical axis wind turbine [PDF]

open access: yes, 2016
Two, three and four bladed phgr-shape Vertical Axis Wind Turbines are simulated using a free-wake vortex model. Two versions of the three and four bladed turbines are considered, one having the same chord length as the two-bladed turbine and the other ...

Core Losses and Torque Ripple in IPM Machines: Dedicated Modeling and Design Trade Off [PDF]

open access: yes, 2009
The proper combination of stator and rotor slot numbers is pursued in the design of interior permanent-magnet (IPM) motors with wide constant-power speed range.

Thrust Force Ripple Reduction of Two C-Core Linear Flux-Switching Permanent Magnet Machines of High Thrust Force Capability

open access: yesEnergies, 2017
Linear flux-switching permanent magnetic (LFSPM) machines are good choices for long stroke applications. These machines deliver high thrust force density in addition to the machine structure where permanent magnetics (PMs) and windings are all on the ...

Assessment of torque components in brushless permanent-magnet machines through numerical analysis of the electromagnetic field [PDF]

open access: yes, 2005
For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air gap.

Coulomb explosion sputtering of selectively oxidized Si [PDF]

open access: yes, 2009
We have studied multiply charged Arq+ ion induced potential sputtering of a unique system comprising of coexisting Silicon and Silicon oxide surfaces. Such surfaces are produced by oblique angle oxygen ion bombardment on Si(100), where ripple structures ...

Coarse-grained simulation of transmembrane peptides in the gel phase [PDF]

open access: yes, 2013
We use Dissipative Particle Dynamics simulations, combined with parallel tempering and umbrella sampling, to investigate the potential of mean force between model transmembrane peptides in the various phases of a lipid bilayer, including the low ...

Performance comparison of conventional synchronous reluctance machines and PM-assisted types with combined star-delta winding [PDF]

open access: yes, 2017
This paper compares four prototype Synchronous Reluctance Motors (SynRMs) having an identical geometry of iron lamination stacks in the stator and rotor.

The physics of wind-blown sand and dust [PDF]

open access: yes, 2012
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols.

Atomic force microscopy (AFM) study of thick lamellar stacks of phospholipid bilayers

open access: yes, 2007
We report an Atomic Force Microscopy (AFM) study on thick multi lamellar stacks of approx. 10 mum thickness (about 1500 stacked membranes) of DMPC (1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine) deposited on silicon wafers.
