Experimental Scaling of Modified Fuel Breakup.
Abstract
A small-scale test configuration was developed for modified fuel breakup and ignition testing. The configuration consisted of a 1/4-inch fuel delivery tube within a 1-inch air atomization pipe followed by a deceleration cone. Photographic evaluation required design of a unique fuel spray photographic chamber which has the capability of photomicrographic, schlieren, and stroboscopic photographic techniques. The chamber employs positive pressurization with diluent air to prevent spray recirculation and fuel deposition on optical components. The spark photographs proved that the breakup phenomenon can be scaled down without obliteration of the dominant rheological effects. Motion pictures of ignition show the same flammability behavior shown in larger scale tests. It is concluded that the concentric tube atomization technique provides a practical method for comparative evaluation of modified fuels on a small scale. (Author)
