A particle method is presented for computing vortex sheet motion in three-dimensional flow. The particles representing the sheet are advected by a regularized Biot-Savart integral in which the exact singular kernel is replaced by the Rosenhead-Moore kernel. New particles are inserted to maintain res
A vortex particle method is developed for simulating two-dimensional, unsteady compressible flow. The method uses the Helmholtz decomposition of the velocity field to separately treat the irrotational and solenoidal portions of the flow, and the particles are allowed to change volume to conserve mas
A new vortex particle-in-cell (PIC) method is developed for the computation of three-dimensional unsteady, incompressible viscous flow in an unbounded domain. The method combines the advantages of the Lagrangian particle methods for convection and the use of an Eulerian grid to compute the diffusion
## Abstract In this research, with a view to threeβdimensional image reconstruction, a method for tracking the coordinates of the tomographic image plane is investigated by drawing attention to the shift and variation of the speckle pattern in the Bβmode image. In this method, the shift vector in t
