Laser radiation - Gas dynamic coupling in the gaz sf6-air laminar

Using an implicit finite-difference technique, numerical results are presented for the radiation gas dynamic interaction associated with CO2 laser radiation absorption in the Sulfr hexafluoride-air laminar compressible boundary layer. This work extends earlier flat plate results to include the stagnation point and downstream region of an axisymmetric body with head-on laser radiation present. The stagnationGet price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price
