@article{(Open Science Index):https://publications.waset.org/pdf/2200, title = {A Further Improvement on the Resurrected Core-Spreading Vortex Method}, author = {M-J. Huang and C-J. Huang and L-C. Chen}, country = {}, institution = {}, abstract = {In a previously developed fast vortex method, the diffusion of the vortex sheet induced at the solid wall by the no-slip boundary conditions was modeled according to the approximation solution of Koumoutsakos and converted into discrete blobs in the vicinity of the wall. This scheme had been successfully applied to a simulation of the flow induced with an impulsively initiated circular cylinder. In this work, further modifications on this vortex method are attempted, including replacing the approximation solution by the boundary-element-method solution, incorporating a new algorithm for handling the over-weak vortex blobs, and diffusing the vortex sheet circulation in a new way suitable for high-curvature solid bodies. The accuracy is thus largely improved. The predictions of lift and drag coefficients for a uniform flow past a NASA airfoil agree well with the existing literature.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {5}, number = {7}, year = {2011}, pages = {1353 - 1358}, ee = {https://publications.waset.org/pdf/2200}, url = {https://publications.waset.org/vol/55}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 55, 2011}, }
