FLOW AROUND TRANSVERSE SLOTS

An inspection analysis of a plane two-scale problem on 
a stationary laminar flow around an array of slots has been carried 
out on the assumption that the internal scale, representing the spacing 
of the slots, is small compared to the external scale of the global 
problem. Topological and asymptotical classifications of the structure 
of a boundary layer have been developed with consideration of the 
rate of the boundary-layer suction and the spacing of the slots. The 
dependence of the multizone structure of a boundary layer with discontinuously 
distributed suction on the width of the slot and the rate of the suction 
was investigated. A mathematical model of a nonviscous compressible-gas 
flow in the weak-interaction and strong-interaction regimes is proposed.
