DESIGN OF AN APPARATUS FOR TESTING THE FLAMMABILITY OF FUEL SPRAYS

An automated small-scale test apparatus was developed for flammability testing of modified fuels. The test configuration consists of a 1/4 inch fuel delivery tube within a 1 inch air atomization pipe followed by a diffuser section. A pressurized 30 gallon air tank supplies the atomization air while a syringe pump provides a specified fuel quantity for all tests. Isentropic calculations and hot wire anemometer measurements characterize the air flow during the transient air release. Oscillograph traces specify the sequencing and timing of events. It is concluded that this transient test is a practical device for modified fuel testing because of its simple construction, well-defined operation, and capability of distinguishing between candidate additives.
