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 ...

This paper investigates the use of a lifting surface method coupled with nonlinear lift curve, vortex lattice (NL-VLM), toward study stall cells on wings. First, Spala...

This paper extends the prescribed wake vortex lattice/line method (VLM) to perform aerodynamic analysis and optimization of dual-rotor wind turbines (DRWTs). A DRWT turbine consists of a large, primary rotor placed co-axially behind a smaller, secondary rotor. The additional vortex system introduced by the secondary rotor of a DRWT is modeled while taking into account the singularities that occ...

An iterative decambering approach for the post stall prediction of wings using known section data as inputs is presented. The method can currently be used for incompressible flow and can be extended to compressible subsonic flow using Mach number correction schemes. A detailed discussion of past work on this topic is presented first. Next, an overview of the decambering approach is presented an...

We propose an efficient and spectrally accurate numerical method for computing vortex lattice structures in fast rotating Bose-Einstein condensates (BECs) with strongly repulsive interactions. The key ingredients of the method is to discretize the normalized gradient flow under rotational frame by Fourier spectral method in space and by backward Euler method in time. Different vortex lattice st...

The phase states and phase transitions in a system consisting of a two-dimensional vortex lattice with defects are studied by the Monte Carlo method. It is shown that a “rotating lattice” phase, which is an intermediate phase between the vortex crystal and vortex liquid phases, is present. The dependence of the temperature of the transition from the rotating lattice phase into a vortex liquid o...

The phase transition ‘‘triangular lattice–vortex liquid’’ in layered highTc superconductors in the presence of pinning centers is studied. A two-dimensional system of vortices simulating the superconducting layers in a high-Tc Shubnikov phase is calculated by the Monte Carlo method. It was found that in the presence of defects the melting of the vortex lattice proceeds in two stages: First, the...
