Laser radiation - Gas dynamic coupling in the insulating gas-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 insulating gas-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

Recovery of Sulfr hexafluoride from air-sf 6 mixtures using sorption on

Adsorptive separation of SF 6 /N 2 mixtures is an important issue since SF 6 is a significant greenhouse gas. Although separation performances should be evaluated under high pressure conditions to find an efficient adsorbent candidate for pressure swing adsorption (PSA) processes, no studies on metal–organic frameworks (MOFs) have focused on SF 6 /N 2 separation at high pressures above 1 bar.Get price
