“…For velocity-vorticity formulations, several studies have appeared in the literature, e.g. Dacles and Hafez [1], Fasel [14], Dennis et al [15], Farouk and Fusegi [16], Napolitano and Pascazio [17], Daube [18], Ern and Smooke [19], Guj and Stella [20], and Guevremont and Habashi [21]. Given an initial distribution of vorticity, the evolution of the velocity and vorticity may be computed by solving Equations (2) and (3) subjected to appropriate boundary conditions.…”
