IllinoisRocstar LLC is a limited liability company founded in 2007 to perform computational engineering analyses for U.S. government agencies and industries. Using the Rocstar suite of integrated simulation software, the members of IllinoisRocstar employ first-principles based physics for high-fidelity numerical analysis of fluid flows, combustion, materials, structures, and their interactions in complex changing geometries. The principals and members of the company are experienced leaders and senior scientists using advanced computation and simulation techniques to understand the implications of three-dimensional fluid-structure interactions on the design and application of engineered devices. IllinoisRocstar seeks to commercialize, extend and implement simulation software developed at the University of Illinois Center for Simulation of Advanced Rockets and other sources.
The figure to the right is a three-dimensional plot of the plume flow from an elliptical stack in a cross-wind. The plot shows the vorticity of the flow, using an LES turbulence model and a 1.8 million element block-structured hexahedral grid. The plume is heated to 900 K, and the cross-flow is ambient air.
The Rocstar simulation suite provides IllinoisRocstar LLC with capabilities to perform engineering simulations in three dimensions of many different types of computational fluid dynamics (CFD) problems, and to couple those simulations with the responses of structures that interact with the fluids.
