EXPERIMENTS IN TURBULENT SOAP-FILM FLOWS: MARANGONI SHOCKS, FRICTIONAL DRAG, AND ENERGY SPECTRA BY

by unknown authors
"... We carry out unprecedented experimental measurements of the frictional drag in turbulent soap-film flows over smooth walls. These flows are effectively two-dimensional, and we are able to create soap-film flows with the two types of turbulent spectrum that are theoretically possible in two dimension ..."

"... Gas Jet-Workpiece Interactions in Laser Machining Laser machining efficiency and quality are closely related to gas pressure, nozzle geometry, and Introduction The assist gas plays an important role in laser machining. It provides a mechanical force to eject the melt from the cut zone and cools ..."

. They report that in some cases underneath the Mach disk, a vortex ring or stagnation bubble may form. This could be a result of the interaction of the jet shock with the normal standoff shock ͓15͔ or a result of the weak shock waves ͑due to nozzle imperfections͒ interacting with the standoff shock ͓16͔
