- Description
- NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a software technology for modeling the fluid flow behavior of an in-line mechanical pressure regulator within a fluid simulation system. The algorithms and code were developed to accurately account for transient flow behaviors that occur at pressure regulators, something static models do not. The pressure regulator model was developed to extend the modeling capability of NASAs commercially available Generalized Fluid System Simulation Program (GFSSP). This pressure regulator modeling software will more accurately reflect real-world conditions throughout the operating regime for two-phase systems as well as single-phase systems. The novel NASA algorithm is more accurate and robust under start-up and transient cases, and monotonically converges on a stable and steady state solution. NASA is looking for development partners, particularly those using or interested in the NASA GFSSP. Typical pressure regulator models assume a steady state, fixed pressures, based on a rearward calculation, which does not reflect real-world transient behavior and system instabilities. To address the shortcomings of typical models NASA developed a forward-looking, time-dependent algorithm that more accurately reflects real-world transients. The subject, patent pending method provides a pressure regulator model that accurately models transient conditions and furnishes a much more realistic simulation of one or more regulators. NASA Langley developed the innovative algorithm to resolve problems with the NASA patented GFSSP. The inventors had discovered inaccuracies in the results provided by the GFSSP pressure regulator model, especially when operating near a fluids vapor dome. The new algorithm modeled a regulator by increasing or decreasing flow, within limits, in response to decreases or increases in downstream pressure, respectively. Although the technology was developed for GFSSP, the algorithm can be adapted to work with other similar commercial packages, either as a component or as a stand-alone plug-in. To express interest in this opportunity, please respond to LaRC-PatentLicensing@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/. These responses are provided to members of NASA Langleys Office of Strategic Analysis and Business Development OSACB for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
