Abstrakt: The plane problem of a viscous laminar flow around elliptical cylinders at an angle of attack is considered. By solving the equations of the laminar boundary layer using the Loytsyansky local similarity method, the shear stress at the boundary of the ellipse and the separation points are found. From the equality of the velocities at the separation points, the circulation is found, and a complete solution to the problem of the velocity and pressure fields outside the boundary layer is constructed. The lift and drag coefficients are found depending on the attack angle and the ellipse axes ratio. The theoretical results are compared with the available experimental data and direct numerical solutions of the Navier–Stokes equations. [ABSTRACT FROM AUTHOR]
