In the present numerical study the stellar winds from both supergiant-components of a
detached close binary system (CBS) are simulated applying methods of the three-dimensional numerical hydrodynamics. The simulated winds collide in the space between the components, forming a stationary shock wave. That shock wave has geometrically intricate shape that consists of several separate filamentary structures. The temperature in the shock wave is about 105K, and the temperature in the space adjacent
to the shock wave is around 104 - 1.5 104K. Away from the line-of-centres the shock wave is curved due to the effect of the Coriolis forces and greatly expands under the gas pressure at that. At a distance of about
two orbital separations from the line-of-centres the shock wave expands so much that it is practically smearing out in space.
