...Eiji Ishii; Masanori Ishikawa; Yoshihiro Sukegawa; Hiroshi Yamada The fuel spray of an injector for automobile engines contains multiscale free surfaces: liquid films formed at the fuel-injector outlet, ligaments generated by liquid-film breakup, and droplets generated from the ligaments within...

...Fei Zheng; Andrey V. Kuznetsov; William L. Roberts; Daniel E. Paxson For many propulsion devices, the thrust may be augmented considerably by adding a passive ejector, and these devices are especially attractive for unsteady propulsion systems such as pulse detonation engines and pulsejets...

... the facility design and the dynamic properties of the tested inducer. The model has been used for evaluating the dynamic performance of a prototype of the LE-7 engine liquid oxygen (LOX) inducer, in tests carried out under given external flow rate excitations. The main results of these calculations...

...W. H. Nurick; T. Ohanian; D. G. Talley; P. A. Strakey The approach taken was to analyze the results in a manner consistent with application by design engineers to new and existing applications, while providing some insight into the processes that are occurring. This paper deals with predicting...

...Gianluca Iaccarino; Stéphane Moreau The Cartesian incompressible RANS solver with immersed boundaries, IBRANS , recently developed at Stanford, has been extended to include conjugate heat transfer modeling and used for the simulation of the electrical motor of an automotive engine cooling fan...

...Venkata Nori; Nelson Lerma; Jonas Gustavsson; Corin Segal; Rene Fernandez The effects of oscillatory backpressure on the air induction system for pulse detonation engines were examined for a two-dimensional, mixed-compression configuration at a freestream Mach number of 3.5. The pressure...

...Diego A. Arias; Timothy A. Shedd This work presents the mathematical model of a complex flow network containing short metering orifices, compressible flow, and two-phase flow in small diameter pipes. It has been developed to study the steady and dynamic flows in a carburetor for small engines...

...J. U. Schlüter; X. Wu; S. Kim; S. Shankaran; J. J. Alonso; H. Pitsch Full-scale numerical prediction of the aerothermal flow in gas turbine engines are currently limited by high computational costs. The approach presented here intends the use of different specialized flow solvers based...
