Abstract

The accuracy and computational efficiency of contour advection schemes for the simulation of two-dimensional inviscid incompressible flows are analyzed. Their comparison with the contour dynamics method is performed. The results obtained show that the semi-Lagrangian contour advection algorithm is very efficient when the relation of the domain size to the characteristic length of the flow is small or when the vorticity field is approximated by a large number of contours. This approach allows one to achieve a higher accuracy with an increase in computational cost.
