Abstract

Air ejector rocket systems, typical of combined cycle engines for space propulsion applications, have been studied within the ESA Future European Space Transportation Investigations Program. The description and validationof the computational fluid dynamics (CFD) algorithm that has been tuned to simulate the behavior of these systems, and the numerical rebuilding of the ejector rocket experimental tests that were carried out at TNO in The Netherlands are given. The computational developments being presented target the problem of turbulent mixing layer simulation, which is one of the leading phenomena that govern flow behavior inside an ejector rocket. Comparison between experimental and CFD data is given for two validation test cases: a two-dimensional turbulent mixing layer and an axysimmetric ejector in cold flow. Then, the numerical rebuilding of the ejector rocket experimental tests is presented, and the results are discussed with regard to the comparison between numerical and experimental data.
