Use of virtual, simulation-base prototyping is starting to be routinely used to streamline and optimize the design of cooling systems required by military ground vehicles. A new generation of integrated simulation tools is however needed to effectively deal with the evolving complexities of the new… More

The proposed project will rectify the current bottleneck in the simulation of 3D magnetic fields around high-current pulsed power devices. In the existing software, fields in the air are approximated by an artificial magnetic diffusion equation, which is both computationally expensive and… More

We propose to develop a stand-alone computational module for seamlessly extending the validity of continuum CFD codes into transitional and rarefied flow regimes. The module will be designed for implementation in to existing legacy codes for use in characterization of high altitude plume flows. The… More

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)… More

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… More

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves in unbounded regions. The accuracy and/or stability of the simulations may deteriorate over long times due to the treatment of the outer boundaries via artificial… More
