Predictions of Vortex-lift Characteristics by an Extended Vortex-lattice Method

Design of Hydrofoil Assisted Catamarans using a Non-Linear Vortex Lattice Method

Extensive experimental investigations of hydrofoil-assisted catamarans have identified the main hydrodynamic parameters affecting the performance of these vessels. Design principles of existing vessels are discussed in the light of these hydrodynamic findings. The experience gained from experimental testing has provided the basis for the development of a non-linear vortex lattice method for des...

Numerical Simulation of Vortex Breakdown by the Vortex-Filament Method

Generalized Vortex Lattice Method for Predicting Characteristics of Wings with Flap and Aileron Deflection

A generalized vortex lattice method for complex lifting surfaces with flap and aileron deflection is formulated. The method is not restricted by the linearized theory assumption and accounts for all standard geometric lifting surface parameters: camber, taper, sweep, washout, dihedral, in addition to flap and aileron deflection. Thickness is not accounted for since the physical lifting body is ...

Vortex fermion on the lattice

The domain wall fermion formalism in lattice gauge theory is much investigated recently. This is set up by reducing 4+1 dimensional theory to low energy effective 4 dimensional one. In order to look around other possibilities of realizing chiral fermion on the lattice, we construct vortex fermion by reducing 4 + 2 dimensional theory to low energy effective 4 dimensional one on the lattice. In e...

Two-dimensional vortex lattice melting.

We report on a Monte-Carlo study of two-dimensional Ginzburg-Landau superconductors in a magnetic field which finds clear evidence for a firstorder phase transition characterized by broken translational symmetry of the superfluid density. A key aspect of our study is the introduction of a quantity proportional to the Fourier transform of the superfluid density which can be sampled efficiently i...
