  This paper presents a comprehensive investigation into the modeling of rotor
wake velocities, in a simplistic manner, using the Viscous Vortex Particle
Method (VVPM). The study aims to accurately simulate wind velocities in the
wake of helicopter rotors while comparing the VVPM with other established
methods such as Momentum theory, Blade element theory, and the Free wake
method. The VVPM is particularly promising due to its ability to simulate the
interaction of rotor blade vorticities with a natural and efficient approach.
The method employs a grid-free Lagrangian formulation, eliminating artificial
numerical dissipation in the solution. To demonstrate the efficacy of the
method, a Python code has been developed, enabling the visualisation of wake
velocities for basic scenarios.
