Even if the condition of water on the earth seems rest, if we look at the fluid particles condition in molecular level or atomic level, fluid particles might be in the condition rotational vortex motion around themselves or in the condition equivalent to rotational motion around themselves, and they act centrifugal forces or equivalent forces to them on the fluid particles vertical upward (radial outward) and their weight of masses that directs vertical downward (radial inward) is supported vertical upward (radial outward) and balanced everywhere all around at every depth along the radial line on the earth.

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.
