Further investigations of combustion of free droplets in a freely falling chamber including moving droplets

For the further investigation of the combustion of free droplets under a zero-gravity condition in a freely falling chamber, the experimental apparatus and technique were improved as follows: Increased duration of zero-gravity condition; observation of moving droplets as well as stationary droplets; and schlieren system to observe the hot gas zone. In addition to n-heptane, ethyl alcohol and benzene were also used as fuels. The effects of the...
