| 초록 |
This work presents an investigation of aerodynamic characteristicsof cold fuel spray injected from a high pressure hollow cone swirl injector into a constant volume chamber. Laser tomography visualization was used to interrogate the fuel and air mixing characteristics and the effect of chamber pressure and temperature increase was analysed. Preliminary results on spray patternation showed that mixing effect tends to increase with the increase of chamber gas density yielding a decrease of spray penetration and a well-defined vortex structure. |
