Abstract Details

2014, Master of Science, University of Toledo, Mechanical Engineering.
Small turbine engines are highly affected by the weight of onboard components during operation. This idea has led to the development of the rotary fuel slinger which acts as the primary fuel delivery system for the combustor. This type of fuel delivery system involves a rotating component or slinger that uses centrifugal forces to propel atomized fuel into the combustion chamber. The atomization properties of the fuel are highly affected by the rotational speeds of the slinger and suffer during engine start-up conditions. Exit orifice designs are being studied in order to conclude an optimal size and shape for uniform droplet size distributions. It is important that the atomized droplets remain within a certain size distribution in order to burn completely and with the highest efficiency possible. Recently, the idea of using pre-manufactured micro atomizing nozzles at the exit orifice has come to realization. The thought is that these nozzles will help maintain a more uniform droplet size distribution even under low rotational speed start-up conditions. To date, there have been no publications on the use of micro atomizing nozzles on a rotary fuel slinger. Therefore, a study was conducted on six different micro iv atomizing nozzles in order to assess their effectiveness in the fuel delivery design process. This study will show various results including droplet size distribution data for a range of certain start-up condition variables. From these results, the small turbine manufacturer may determine a suitable nozzle for their system or may choose to continue research on a specially designed exit orifice that may better fit their needs.
