...Jaehyoung Jeon; Moongeun Hong; Yeoung-Min Han; Soo Yong Lee Gas-centered swirl coaxial injectors have become an important subject of study for staged combustion rocket engines with hydrocarbon fuels. While these injectors are employed successfully in rocket engines, it is very rare to find...

...Eric Goncalvès; Regiane Fortes Patella; Julien Rolland; Benoit Pouffary; Guillaume Challier This study was led in collaboration with the French Space Agency (CNES) and the Rocket Engine Division of Snecma. The main aims were the simulations and the analyses of cavitating flows in the rocket engine...

...Joseph Majdalani; Michel Akiki In this work, we present two simple mean flow solutions that mimic the bulk gas motion inside a full-length, cylindrical hybrid rocket engine. Two distinct methods are used. The first is based on steady, axisymmetric, rotational, and incompressible flow conditions...

...S. Duplaa; O. Coutier-Delgosha; A. Dazin; O. Roussette; G. Bois; G. Caignaert The startup of rocket engine turbopumps is generally performed only in a few seconds. It implies that these pumps reach their nominal operating conditions after only a few rotations. During these first rotations...

... developed for simulating rocket engines and propulsion systems. The solution procedure is coupled with a state-of-the-art real-fluid property database so that both compressible and incompressible fluids may be considered using the same procedure. The numerical techniques used in this procedure are described...

...Toshiya Kimura; Yoshiki Yoshida; Tomoyuki Hashimoto; Mitsuru Shimagaki Unsteady cavitation phenomena such as rotating cavitation and cavitation surge are often observed in a turbopump inducer of a rocket engine, sometimes causing undesirable oscillation of the system. Investigation...

...Benoît Pouffary; Regiane Fortes Patella; Jean-Luc Reboud; Pierre-Alain Lambert The cavitation behavior of a four-blade rocket engine turbopump inducer was simulated by the computational fluid dynamics (CFD) code FINE∕TURBO ™. The code was modified to take into account a cavitation model based...

...R. Fortes-Patella; O. Coutier-Delgosha; J. Perrin; J. L. Reboud The cavitation behavior of a four-blade rocket engine turbopump inducer is simulated. A two-dimensional numerical model of unsteady cavitation was applied to a blade cascade drawn from an inducer geometry. The physical model is based...

...Vineet Ahuja; Ashvin Hosangadi; Jeremy Shipman; Russell Daines; Jody Woods The safe and reliable operation of high-pressure test stands for rocket engine and component testing places an increased emphasis on the performance of control valves and flow metering devices. In this paper, we will present...
