There is currently national interest in development of high-speed propulsion systems (eg,
ramjet/scramjet combined cycle) at NASA (eg X-43) and the DoD (eg HyFly). The recent …

Wind-US is a computational platform which may be used to numerically solve various sets of
equations governing physical phenomena. Currently, the code supports the solution of the …

A one‐step, a two‐step, an abridged, a skeletal, and four detailed kinetic schemes of
hydrogen oxidation have been tested. A new skeletal kinetic scheme of hydrogen oxidation …

Over the last decade significant new technologies have been developed which allow the
scientist/engineer to design reliable programs for simulating the complex physics involved in …

Grid independence is frequently an overlooked item in CFD analyses. Often an attempt is
made to perform due diligence towards this end, but time and resource constraints prevent …

Two aspects of PDE design and operation are examined using time accurate CFD and
Boeing's PDE cycle deck, DECADE. First, the effect of engine reaction ratio is examined. The …

Increased black-box software use without adequate software literacy can lead to improper
results and potentially disastrous consequences. Furthermore, such software is often …

The ability of the WIND Navier-Stokes code to predict the physics of multi-species gases is
investigated in support of future high-speed, hightemperature propulsion applications …

The scramjet is the supersonic-combustion ramjet engine operating in the hypersonic
regime. Recently, importance of designing regenerative cooling system is highlighted for …

A generic, multi-zone boundary condition procedure has been developed for computational
fluid dynamics (CFD) analyses of propulsion flowfields. The zonal interface scheme …
