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 freely and some collision states and burning characteristics are investigated. We use n-hexadecane, methanol, ethanol, and propanol in the first part of this experiment, and then use hexadecane and ethanol-MTBE(or beneze)-premixture in the second part. Then we will compare the results of these two parts.
According to our experiment results, the combustion states of non-mixable n-hexadecane/methanol droplets is always micro-explosion in adhesive mode. The occurrence of micro-explosion will increase burning rate. In discussion on the n-hexadecane and methanol, we find strong micro-explosion and the zone of micro-explosion in 40%~90% in n-hexadecane volume ratio probably. In the second part of this experiment, we find that if we join the MTBE or beneze of the suitable volume ratio, can increase burning state. But if we join too much MTBE or beneze, it will make immiscible droplets become to multiple miscible droplets.
