Influence of Issued Jet Conditions on Mixing of Confined Flows
Chemical Engineering Transactions, 2013 The development of the velocity and scalar fields in a coaxial jet mixer has been experimentally investigated applying simultaneously Particle Image Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF) methods.

A Molecular Counterpart to the Herbig-Haro 1-2 Flow [PDF]
, 1999 We present high angular resolution (12"-24") and high sensitivity 12CO and 13CO J=2-1 and J=1-0 observations of the HH 1-2 outflow. The observations show the molecular counterpart, moving with a velocity of approx.
