Micafluid SF6-Air Transfer

Micafluid SF6-Air Transfer

A cubic relationship between air‐seaBubbles are thought to enhance gas transfer by exchange into or out of the bubbles and increase turbulence when the bubbles impinge upon the air-water interface [McGillis et al., 1995; WooIf, 1997; Asher and Wanninkhof, 1998]. Gas transfer into or out of bubbles is a function of gas solubility, thus the proposed relationship is unique for CO2.

    2016-5-26Products SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).

  • CO2 laser absorption in SF6-air boundary layers - NASA/ADS

    The injection of gaseous SF6 into aircraft and missile boundary layers can attenuate the 10.6-micron radiation typical of CO2 laser beams. This absorption of laser radiation diminishes with increasing temperature, however. The INJECT boundary layer code has been modified in an effort to predict CO2 laser absorption by SF6 in planar, turbulent boundary layers.
