FLOW VISUALIZATION WITH FOG
The below figures show records of flow
visualization with the help of fog obtained in
glassworks and in the test room.
Research into heat stress reduction of
glass-making line operators
Research into flow shapes from outlets in the
test room

INTERFEROMETRIC VISUALIZATION
The following figures show interferometric
records of flow visualization obtained in scale
models in our optical laboratory.
Research into free non-isothermal jets from
outlets
Research into non-isothermal jets from outlets
around obstacles

EVALUATION OF INTERFEROGRAMS
The interferograms are processed and evaluated by
our Interfer software.

DETERMINATION OF JET BOUNDS
The Interfer-Visual 4.0 software also works with
video sequences and determines
? Courses of jet bounds ? Distribution of
intensity in a cut, etc.

TRANSFORMATION OF RECORDS
The below figures show application of the
function of Addition of two images and the
function of Interferogram for determination of
jet bounds.

CONCLUSIONS

• Our experiments are implemented under laboratory
  as well as field conditions.

• Our software includes functions for evaluation of
  records obtained both interferometrically and
  with the help of fog or smoke.

CONCLUSIONS ? ? ? ?

• Boundaries and shapes of air flow are typical
  results of these experiments and can serve as a
  basis for evaluation of other values.
• The software increases efficiency of the research.
