While DNS of complex flow phenomena is a routine practice nowadays, the analysis tools lack the sophistication to utilize the abundance of data generated, for they are devoid of physics-based data extraction and feature-detection protocols. The current effort proposes an automated and intelligent co-processing data-mining framework, in the form of an API, that detects and tracks flow features of s ...

A tightly coupled multi-physics framework is proposed for computational aerothermoelastic simulations of hypersonic aerospace vehicles. The multiphysics framework will be developed, validated and demonstrated by enabling variable degree of coupled interactions between non-linear flexible structures, aerodynamics, and heat transfer modules. The framework will be developed by leveraging CFDRC''''s C ...

The design of future hypersonic vehicles requires detailed understanding of flow regimes ranging from rarefied to continuum. Moreover, hypervelocity flows are characterized by high temperatures, excitation of vibrational level of molecules, nonequilibrium dissociation, and ionization. The goal of this project is to develop unified kinetic/continuum solution methods with proper domain decompositio ...

In this program, CFDRC will develop a tool-kit for prediction of ignition delay of hypergolic energetic ionic liquids (EIL). Recently EILs have attracted considerable attention as next generation bipropellants to replace toxic monomethylhydrazine (MMH)  Due to their low vapor pressures, they are safer to handle and transport, and more environmentally friendly than MMH. Accurate prediction of the ...

The overall objective of the Phase II effort is to design and implement the BANDIT software platform that utilizes structured and unstructured intelligence data for the creation, visualization, and quantitative analysis of terrorist networks. BANDIT will ultimately serve as an enabling technology for conducting offensive operations against terrorist networks by objectively identifying individuals ...

Flow fluctuations in the flame-holder cavity affect its stable operation that can lead to degradation of its performance. Efficient cavity operations can be enhanced through active control of injection of air and fuel mixtures. We propose to design and validate a novel Model-Free Direct (feedback) Control system to ensure stable cavity operation in the subsonic regime with smooth transitions to su ...

ABSTRACT: The proposed project will remove the computational bottleneck in the currently adopted numerical treatment of exterior 3D magnetic fields around high-current pulsed power devices. Existing simulators introduce computationally expensive and nonphysical magnetic diffusion in the exterior region. In contrast, our approach is physically and mathematically rigorous and dramatically improves ...

ABSTRACT: Digital Fusion Solutions and its partners North Carolina State University and Kyma Technologies will undertake the development of a wide band-gap (WBG) semiconductor based laser induced semiconductor switch (LSS). By leveraging expertise in fields of semiconductor manufacturing, antenna design, and physics in the terahertz frequency regime a down selection of materials will be done with ...

The Unmanned Systems market is exploding with applications, products and services. For example, an increasing number of Unmanned Aerial Systems (UASs) are serving the military, commercial and research markets today. However, these systems are generally limited to supporting a single particular sensor, payload, or concept of operation assigned at the design stage of development. Expansion of their ...

We are proposing to develop a variable radius of curvature mirror (VRM) produced from carbon fiber reinforced polymer (CFRP) composite materials. This will support a compact, lightweight, robust imaging system for space platforms than can survey a wide area for situational awareness and optically (NOT electronically) magnify an area-of-interest almost instantly without macroscopic motion.  Conven ...
