A numerical study of premixed propane/air flame propagation in a closed duct is presented. A dynamically thickened flame (TF) method is applied to model the premixed combustion. The reaction of propane in air is taken into account using a single-step global Arrhenius kinetics. It is shown that the premixed flame undergoes four stages of dynamics in the propagation. The formation of tulip flame phenomenon is observed. The pressure during the combustion process grows exponentially at the finger-shape flame stage and then slows down until the formation of tulip shape. After tulip formation the pressure increases quickly again with the increase of the flame surface area. The vortex motion behind the flame front advects the flame into tulip shape. The study indicates that the TF model is quite reliable for the investigation of premixed propane/air flame propagation.

The theoretical substantiation of pyloroplasty as a therapeutic method in adults is based on the provisions, which are still very problematic today. Russian authors (Breitsev, Grekov et al.), who first proposed this operation in adults, set indications for this kind of intervention very broadly and considered it indicated not only for pylorospasm without visible ulcer, but also for ulcers of the small curvature and for ulcers of the 12th bowel. At the same time these authors proceeded from the position that pylorospasm is the central point in the pathogenesis and course of ulcers and they considered its elimination to be very important in the operative treatment of ulcers.
