The oxidizer angle and fuel angle are the angles between the respective fluid streams to a normal line of the injector plate, as shown in Fig. 4. These angles are calculated by balancing each of the stream’s lateral momentums to achieve a desired resultant angle. For a resultant angle of 0, the angles would be chosen such that each stream had the same (but opposite) momentums. They are also constrained by specifying a desired impingement angle.
