- Abstract
The paper presents the results of experimental research of kerosene injection into the high speed nitrogen flow of a model of a detonation chamber. Kerosene was injected into the rectangular section of the model of the chamber, which had a width of 20mm. A plain orifice kerosene injector of various diameters was used. The injector was set perpendicular to the nitrogen flow. The nitrogen was injected through a slot of a certain size that created a choked flow. Measurements of the nitrogen velocity distribution and numerical calculations for the chamber were performed in order to obtain data on the nitrogen speed inside the chamber. The nitrogen flow velocity in the experiments was in the order of 50-250 m/s, depending on the distance between the Prandtl probe and the inner wall. Measurements of the diameter of droplets injected into the model chamber were also taken. Highspeed photography with a back light was utilized in the droplet diameter measurements. The values of the SMD, obtained for the stream of cold nitrogen (about 290 K), were of the order of 33-38 mm. This provided information about the size of the droplets and their spatial distribution, which are key elements in the designing of the detonation chamber.
