in this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. experiments were carried out by planar imaging and particle image velocimetry (piv) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and fue...

In the present paper, results for fluid flow, temperature and air humidity experimental measurements innovative energy recovery counterflow air-to-air heat exchanger have been shown. For low outdoor temperatures case, frost formation is also observed analysed. Base on of analysis temperature, total efficiency are presented. The showed that flow rate, system significantly drop down under unfavou...

Abstract In order to broaden the stable working range of air-breathing continuous rotating detonation engine and explore influence combustor configuration on propagation characteristics wave, cavity-based annular is introduced. Air-breathing experiments are conducted with non-premixed ethylene air. A tri-propellant air-heater used imitate outlet parameters intake Ma4/20km. The designed mass flo...

During the intake process, working volume of cylinder is filled with a fresh charge. As noted, charge consists air in diesel engine, and engines ignition from an electric spark (gasoline carburetor or gasoline fuel injection, as well gas) – mixture vapors light combustible gas.
