DOPPLER GLOBAL VELOCIMETRY. RANGES OF ACCESSIBLE VELOCITIES. PART Ⅱ: NUMERICAL APPLICATIONS

摘要

The Doppler Global Velocimetry (DGV) is a velocity measurement method in fluids based on the Doppler shift generated by an assembly of particles illuminated by a coherent source. The collected very small frequency shifts that contain velocity information are decrypted by means of an absorption linear molecular filter (ALF) - a glass cell filled with iodine vapor - located in front of the receptor. Due to the combination of geometry and spectroscopy, the knowledge of the accessible velocities in the entire zone of interest requires numerous mathematical developments exposed in Part I. This paper deals with numerical applications where three directions of observation and one direction of illumination are considered.
