TY - JOUR T1 - An artificial boundary condition for the vortex movements in two dimensions AU - Q. Cheng JO - Numerical Mathematics, a Journal of Chinese Universities VL - 2 SP - 150 EP - 163 PY - 2006 DA - 2006/05 SN - 15 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/nm/8024.html KW - AB - An approximate artificial boundary condition based on a boundary integral equation is designed for the vortex movements. Point vortex and cloud in cell methods are used in numerical simulation of vortex motions. The numerical experiments show that the approximate artificial boundary condition is useful and sufficiently accurate in hydrodynamics.
