A new multi-phase model for low speed gas/liquid mixtures is presented; it does not require
ad-hoc closure models for the variation of mixture density with pressure and yields …

Numerical simulations of cavitation in liquid nitrogen and liquid hydrogen are presented;
they represent a broader class of problems where the fluid is operating close to its critical …

A method is presented for redesigning a centrifugal impeller and its inlet duct. The double‐
discharge volute casing is a structural constraint and is maintained for its shape. The …

Preconditioning techniques that are used to alleviate numerical stiffness due to low Mach
numbers in steady flows have not performed well in unsteady environments since the …

The effect of a gap between an inlet duct and a rotating impeller in a centrifugal fan is often
neglected in the impeller design calculations or design-related computational fluid dynamics …

Simulations of an uni-element, shear coaxial injector configuration with liquid nitrogen in the
inner tube mixing with a co-flowing warm nitrogen gas stream are presented; the chamber …

This paper presents a parallel remeshing algorithm for distributed-memory architectures. It is
an iterative parallel algorithm that divides the areas to be remeshed into multiple pieces …

The development of a unified tightly coupled multi-phase computational framework is
described for the analysis and design of cooling spray nozzle configurations on the flame …

Previous efforts, for which high performance computing modernization program (HPCMP)
computer time was utilized, employed state-of-the-art computation fluid dynamics (CFD) …

Valve systems in rocket propulsion systems and testing facilities are constantly subject to
dynamic events resulting from the timing of valve motion leading to unsteady fluctuations in …
