| Ringkasan: | The Schlieren technique remains to be one of the most powerful technique to visualize the flow and
it is relatively easy to implement, high and variable sensitivity, low cost and its used conventional
of light. This technique allows us to see the invisible of the optical inhomogeneities in transparent
media like air, water and glass that otherwise cause only ghostly distortions of our normal vision.
This research investigates the mixture formation and flame development of biodiesel fuel using the
Schlieren optical visualization principle. This method can capture spray evaporation, spray
interference, mixture formation and flame pattern clearly with real images. During the experiment,
the camera lens was used with telephoto lenses (Nikon 70-300mm f/4-5.6G) in order to capture a
large amount of light especially the low flame intensity during the initial flame development. The
flame development was captured with color images from a color digital video camera. This method
can capture the flow of fluids of varying density, such as spray evaporation, spray interference and
mixture formation clearly with real images. The result shows that the mechanism of fuel-air mixing
and a better comprehension of combustible mixture that can give valuable information to improve
and optimize the combustion process. |
