Existing data on transient turbulent jet injection in to large chambers demonstrates self-similar behavior under a wide range of conditions including compressibility, thermal and species diffusion, and nozzle under expansion. The Jet penetration distance well downstream of the virtual origin is proportional to the square root of the time and the fourth root of the ratio of nozzle exit momentum flow rate to chamber density. The constant of proportionality has been evaluated by invoking the concept of Turner that the flow can be modeled as a steady jet headed by a spherical vortex. Using incompressible transient jet observations to determine the asymptotically constant ratio of maximum jet width to penetration distance, and the steady jet entrainment results of Ricou and Spalding, it is shown that the penetration constant is 3 ± 0.1. This value is shown to hold for compressible flows also, with substantial thermal and species diffusion, and even with transient jets from highly under-expanded in which, as in diesel engine chambers with gaseous fuel injection, the jet is directed at a small angle to one wall of the chamber. In these tests, with under expanded nozzles. Observations of transient jet injection have been made in a chamber in which, as in diesel engine chambers with gaseous fuel injection, the jet is directed at a small angle to one wall of the chamber. In these tests, with under-expanded nozzles it was found that at high nozzle pressure ratios, depending on the jet injection angle, the jet penetration can be consistent with a penetration constant of 3. At low pressure ratios the presence of the wall noticeably retards the penetration of the jet.

Common-rail pipe is an important component of fuel injection system, whose inner cavity is hidden and requires a high precision. So that the general mechanical processing is difficult to achieve, while abrasive flow machining just be able to solve this problem. In this article, the three-dimensional model of common-rail pipe is established and meshed by GAMBIT, next the mesh file is read into FLUENT, and then the Mixture model is used for numerical simulation. By analyzing the simulation results, we can get how will the pressure difference between inlet and outlet, the volume fraction of abrasive, and the processing order impact on the processing quality. Finally, a reasonable processing program is proposed for the common-rail pipe.
