Abstract: The results of numerical modeling on a basis of Euler equations of a thin limited length low-density channel effect upon supersonic flow past cylinder body with complicated cavity are presented. Behavior of front drag force and total drag force has been investigated. Mechanism of arising two or three minimums in dependence of front drag force on time connected with eddies generation inside the cylinder shock layer is established. New results on impulse behavior of stagnation parameters for the process of the rarefacted domain effect on the supersonic streamlining cylinder blunt body have been obtained. Mechanism of the peaks arising concerning with generation of the triple configuration near the front surface of the body is established.
