Laser radiation - Gas dynamic coupling in the Sulfr hexafluoride-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

Scharfenberg coupler - Wikipedia

The Scharfenberg coupler (German: Scharfenbergkupplung, abbreviated Schaku) is a commonly used type of fully automatic railway coupling.. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit systems.Get price
