In this paper, in order to introduce recent development of a Lagrangian vortex method which is based on Biot Savart law, mathematical background and numerical procedure of the method is explained. A topic of application of the vortex method into the field of vehicle aerodynamics is introduced by explaining results of calculation of unsteady flow around a bluff body, which is the well-known ASMO. The aerodynamics of this model is studied by analyzing how forces, pressure distributions, and velocity fields varied for different configurations with and without wheel segments. And it is finally concluded that the Lagrangian vortex method is expected to provide researchers and engineers with a completely grid-free and easy-to-handle CFD technology in the field of vehicle dynamics.
