National Science Foundation
Our objective was to create a state-of-the-art CFD capability built upon the Vorcat technology for applications involving two-phase, particulate, incompressible turbulent flow fields. In this initial Phase I, the work focused on achieving two goals: (i) To analyze, develop, and implement the necessary modifications to the vortex method to include the coupled two-phase, fluid-particulate simulation capability and, (ii) To perform limited testing and validation studies as time permits. In particular, to compare a passive scalar model (with or without external forces) with a two-way coupling model for simple settings.

The objective of this project was to simulate low-speed, turbulent aerodynamic flows using the Vorcat implementation of the three-dimensional, viscous vortex method. Vorcat represents a fundamentally different methodology for turbulent flow prediction compared to traditional RANS and LES techniques, which have been developed within the sphere of computational fluid dynamics (CFD) over many years.

Vorcat, Inc. proposed to achieve dramatically improved predictions of fluid flow through the application of innovative algorithms and computational methods. Fluid engineering - designing systems for the optimum flow of fluids - plays a major role in modern engineering, from the design of engines and gas turbines to airfoils, automobiles, ship hulls, electronic packaging, HVAC systems, and industrial processing equipment.
Defense Threat Reduction Agency (DTRA), Department of Defense, SBIR Phase I Contract
The objective of this Small Business Innovation Research Phase I project was to devise accurate techniques for predicting turbulent mixing with a view toward estimating the effectiveness of strategies for neutralizing bio/chem hazards. Substantial progress by Krispin Technologies, Inc. in developing 3D vortex methods for turbulent flow simulation as part of a DOE supported SBIR Phase II project was leveraged to yield immediate application to realistic hazard scenarios of interest to DTRA.
Ford Motor Company - Research Contract
The unique software Vorcat, which is based on a fast parallel vortex method, was employed to perform a timeaccurate simulation of the flow in a pressure regulator spool valve from an automotive automatic transmission. The spool valve experiences flow forces, which affect its axial motion and radial clearance. In this work, detailed flow field information, including velocity, vorticity, and pressure distributions were computed for spool valve openings of 1mm and 0.25mm.
U.S. Department of Energy
This work aimed at the development of a versatile, efficient, and physically accurate commercial software for the solution of a broad range of turbulent flows encountered in energy engineering. In Phase I, the effort focused on achieving dramatic improvements both in speed and efficiency of a Fast Multipole Method (FMM) for computing the velocity field produced by the three-dimensional vortex elements: the most computationally intensive part of the complete algorithm.
