Application of the Laser Doppler Velocimetry to Polymer Melt Flow Studies

  • H. Kramer

Laser Doppler velocimetry (LDV) is a new tool for fluid dynamics studies /1/. By LDV the velocity vector field can be measured without disturbing the flow itself. However, in polymer melt fluid dynamics, difficulties arise because of temperature problems, the relatively high pressure involved, and the often extremely slow flows. In this’ paper a LDV system is described which was set up especially for polymer melt flow investigations.
