Below the injector nozzle is shown with the holes numbered and their orientation with an axis. The J2715 standard orientation convention has been used by the ECN Spray G community with z = 0, y = 0, x = 0 defined as the tip of the nozzle. Sample CFD meshes and surface geometries are available for the nozzle and hole internal passages.
