Vortex Methods for Fluid Simulation in Computer Graphics
… simulation adds to graphical applications. Vortex methods are receiving increasing attention from the computer graphics community for simple and direct modeling of complex flow phenomena such as turbulence. However, vortex methods have not been developed yet to the level of other techniques …

Computational simulation of buoyancy-driven flows using vortex methods
A new vortex method for simulating two-dimensional buoyancy-driven flows is presented. This Lagrangian method utilizes a discrete representation of the known density field along with the vorticity transport equation and Boussinesq approximation to yield the baroclinically-generated vorticity field, …

A self corrective vortex fluxing method for viscous fluid structure interaction problems
… deforming geometries. Here we combine remeshed vortex methods with a panel method to design a new Vortex Fluxing scheme that uses no special treatment of flow properties at the boundary. It was found that the panel method is capable of correcting any spurious vorticity flux into the wall during …

A fast 3D particle method for simulations of buoyant and reacting flows
… in several areas related to three dimensional vortex methods and their application to multiphysics problems. The first is the solution of a generic scalar transport equation by advecting and diffusing the scalar gradient along a particle trajectory and onto a mesh, respectively, and recovering …

A simplified vortex sheet roll-up method for formation flight
… parameter as well as a truncation of the vortex sheet in the highly rolled-up areas are introduced in order to stabilize the computations. The trailing wing is simply modeled as a lifting line, and its induced drag is computed thanks to a near-field analysis. The results are compared to …

Analytical Unsteady Aerodynamic Models for Horizontal Axis Wind Turbines
… test data. The unsteady wake is modeled using vortex methods. The analysis covers unsteady loading due to fast pitch change at constant wind speed, and varying wind speed at constant pitch. The analysis can be extended to more complex conditions. The work starts by modeling dynamic inflow …
