Abstract

Some theoretical and experimental results are presented for axisymmetric cavity flows generated by a ring type wing. These flows are known as Lighthill-Shushpanov ones. They can be analyzed using the vortex singularity technique for «body-ring wing-cavity» combinations. A numerical solution of'integro-differential equations is carried out applying spline functions to cavities with with positive and negative cavity numbers. Experimental results demonstrate efficiency of the technique for cavity flows generation.
