Theoretical analysis and engineering modeling of flowfields in clustered module plug nozzles

The fluid dynamics of clustered module plug nozzles features nontrivial behaviors. The goal of this study is to point out some of the most important fluid dynamic aspects, to provide their detailed analysis by considering both the theoretical and the experimental points of view, and finally to develop engineering models capable of predicting the nozzle behavior and performance by easily applied mathematical relationships. Assessment of the quality of the engineering models has been performed by comparison with available experimental data.
