The fact that the BiGlobal method is viscous, and uses a finite area vortex model, gives rise to results somewhat different from the point vortex model. It adds more parameters to the problem, but is more realistic.}, publisher = {American Institute of Aeronautics and Astronautics}, title = {BiGlobal and Point Vortex Methods for the Instability Analysis of Wakes}, doi = {10.2514/6.2013-2820}, author = {Tendero Ventanas, Juan Ángel and Paredes González, Pedro and Roura Sues, Miquel and Govindarajan, Rama and Theofilis, Vassilios}, }
