Phase 2 SBIR

Agency: Navy
Topic: N132-092
Budget: 01/01/15 - 12/31/15

A multi-scale Lagrangian-Eulerian algorithm has been developed during Phase I to determine the vorticity confinement term for rotorcraft Computational Fluid Dynamics (CFD) computations. Similar to the Large Eddy Simulation approach, the present algorithm simulates the large scales in the flow field and models the unresolved small scales like the...

Agency: Navy
Topic: N132-092
Budget: 10/16/13 - 04/28/14

Similar to the Large Eddy Simulation approach, the proposed approach simulates the large scales in the flow field and models the unresolved small scales li...

Phase 1 SBIR

Agency: Air Force
Topic: AF131-162
Budget: 08/15/13 - 05/14/14

ABSTRACT: This SBIR project proposes to develop a computational aeroelasticity tool for improving the prediction of both aerodynamic forcing and aerodynamic damping and thereby resonant stresses in turbine components. This will be achieved by developing an interface between our CFD software, FlowSimulatorTM, and a commercially available FEM soft...

Phase 2 SBIR

Agency: Navy
Topic: N08-118
Budget: 06/12/13 - 06/13/14

This Small Business Innovation Research project proposes to develop a hybrid Cartesian grid/gridless solver for fast prediction of store separation. In this approach, multi-block structured Cartesian grids with varying grid resolution are used to cover the majority of the computational domain except near the body surfaces for taking advantages o...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-1-A2.09
Budget: 01/01/11 - 12/31/11

This SBIR project proposes to develop a computational tool for helicopter rotor noise prediction based on hybrid Cartesian grid/gridless approach. The uniqueness of this approach is to achieve fully automated grid generation without grid overlapping. As a result, the resulting software will enjoy great ease of use with minimum human interference...

Phase 1 SBIR

Agency: Navy
Topic: N103-195
Budget: 11/19/10 - 05/19/11

This SBIR Phase I project proposes to develop a reduced-order model (ROM) of rotor-airwake aerodynamic coupling for further incorporation into a real-time flight simulator. A CFD rotor-airwake database will be used to design the reduced-order model. The output of the algorithm is the complete flow field (U, V and W velocities at all grid points)...

Phase 2 SBIR

Budget: 05/06/10 - 05/05/12

This Small Business Innovation Research project proposes to develop a hybrid Cartesian grid/gridless solver for fast prediction of store separation. In this approach, a Cartesian grid is used to cover the majority of the computational domain except near the body surfaces to take advantages of ease of grid generation and computational efficiency ...

Phase 1 SBIR

Agency: Air Force
Topic: AF083-268
Budget: 03/04/09 - 12/01/09

This SBIR Phase I project proposes to develop an accurate viscous CFD algorithm which can include various small gaps between both static and moving components into the analysis. It is not an easy task to model those small gaps in the current CFD codes due to the geometric proximity, especially for moving components. However, those small gaps may...

Phase 2 SBIR

Agency: Defense Advanced Research Projects Agency
Topic: SB072-006
Budget: 12/15/08 - 03/14/11

This SBIR project proposes to develop a gas-kinetic CFD solver for separated turbulent flow simulation. After successfully developing prototype two-dimensional gas-kinetic BGK-NS/Burnett solvers and demonstrating the benefits of using higher-order hydrodynamic equations for separated turbulent flow simulation in Phase I, the technical objective ...

Phase 1 SBIR

Agency: Navy
Topic: N08-118
Budget: 08/20/08 - 02/20/09

This SBIR Phase I project proposes to develop an efficient Computational Fluid Dynamics algorithm for store separation prediction. Compared with overset grid approach, the proposed approach avoids the tedious process for fixing the so-called orphan points , the failed interpolation grid points. Compared with dynamic unstructured grid approach w...
