Modeling of potential flows with unknown boundaries on the basis
of stationary discrete vortices
O. A. Averkova, I. N. Logachev, K. I. Logachev Belgorod Shukhov State Technological University
Abstract:
A method to model the detached flows at the inlet of a suction port in multiply
connected regions with cuts (fine visors) is proposed. The method allows one to construct
free streamlines and velocity fields and to determine the local drag coefficient at the
inlets of such channels. The reliability and adequacy of the method are demonstrated
by comparison with numerical results obtained by the Zhukovskii method and with
experimental data. A number of dependencies are found between the detached flow
parameters at the inlet of a plane channel with two visors and their location and
geometric sizes.
Keywords:
detached flow; method of discrete vortices; local drag coefficient.
