| Abstract: | Steady problems of a circulation flow around bodies by a flow of a heavy liquid bounded by a free surface and a straight bottom
are solved. The method of complex boundary elements is used, which is based on the integral Cauchy formula written for a complex-conjugate
velocity. Results of numerical calculations of the flow around a circular contour and the Joukowski airfoil are presented.
Shapes of the free surface and the most important hydrodynamic characteristics of the process (velocity circulation over the
airfoil and the lifting force and its moment relative to the sharp edge of the airfoil) are given.
