Investigation of unsteady vorticity layer eruption induced by vortex patch using vortex particles method

Henryk Kudela, Ziemowit Miłosz Malecha
The study of eruption of the vortex boundary layer phenomenon due to motion of the patch of vorticity above the wall is presented here. The vortex particle method is chosen to investigate the phenomenon. It shows the eruptive character of the vortex induced boundary layer. Such visualization is possible through the use of the vortex particle method. Description of the numerical method is given. The obtained numerical results are confronted with the numerical and analytical data of other researchers, conforming to a great extent with the conclusions.
