The Diffused Vortex Hydrodynamic (DVH) is a meshless 2D Lagrangian incompressible Particle Vortex Method. In this study the DVH will be applied to simulate viscous flows around five different bodies at Re=10,000. In order to show how the DVH method works, simulations about five different geometries will be discussed: (i) a cylinder with circular section, (ii) a cylinder with squared section, (iii) a narrow elliptical profile, (iv) a thick elliptical profile and (v) a NACA0010 profile. All the five considered geometries develop a complex vortical wake and, moreover, the last three profiles, having a 30 degrees angle of attack, give rise to flow separation on the suction side.
