Abstract
Experiment applies Ink-Jet Printing method to generate dual free droplet streams and collided along their path as they fall. Then the collided droplets will fall into the combustion chamber. We can observe the characteristics of combustion : ignition delay、burning time、burning rate、flame shrinking and micro-explosion. We use diesel fuel, bio-diesel, and water in the first part of this experiment. In different droplet size, oxygen volume fraction observe the characteristics of combustion and micro-explosion. Use bio-diesel and methanol, ethanol in the second part. Then we can observe the characteristics of premixture and collision.
According to the experiment results, the combustion states of water and bio-diesel are water droplet micro-explosion and extinction. The probability of the occurrence of micro-explosion will increase when the water droplet size decrease. Then find flame shrinking in this experiment. The methanol, ethanol and bio-diesel collision、combustion、micro-explosion stability better than diesel.
