Validation of Integral Method for Numerical Prediction of Hybrid Rocket Internal Ballistics

Journal of Fluid Science and Technology, 2013
In order to design hybrid rocket engines, we developed a numerical prediction method which describes the internal ballistics, thus the solid fuel regression rate. In order to obtain a fast code, simple but efficient models have been implemented.
