Vortex Lattice Method, Vortex Particle Method, Unsteady AerodynamicsAbstract
The concept of vorticity-dominated flow has been widely used in the formulation of aerodynamic simulation methods. This work extends the unsteady vortex lattice method (UVLM) by incorporating the vortex particle method (VPM), a hybrid model that combines particles and vortex segments. The use of VPM eliminates the wake mesh structure, but it can be unstable and may require additional considerations for implementation. In this regard, a series of cases are analyzed to highlight the benefits, identify potential drawbacks, and provide recommendations on the use of VPM. The results contribute to understanding the challenges associated with VPM implementation and offer valuable insights into leveraging its advantages in various aerodynamic interaction applications and flows around submerged bodies.
