Definitions

  • the proposed design of the combustion chamber is based, among other things, on the spectacular merging and mixing behavior of colliding, with opposing Rotating, rotating, subcritical vortices. This phenomenon occurred on Flow behavior in front of and in radial outlet pipes of steam turbines discovered. It is shown there that only when radial outlet pipes are attached A loss-free outflow of the rotating air is possible while losses occur due to swirling in simple openings. A detailed look at the behavior of the air flow before and in one Such a radial outlet pipe shows that two pipes with opposite directions in front of the pipes Rotating, rotating subcritical vortices collide, and the rotation of the two vertebrae within a distance of less than one Completely cancel each other out.
