Customers in automobile and aircraft engine companies, petrochemical companies and energy companies could take advantage of the GPU algorithms to enhance their combustion CFD capabilities for engine design or process optimization. DOE, DOD and NOAA researchers could also utilize these algorithms for a wide range of applications, including combustion modeling, propellant and alloy formation, or atmospheric and air pollution modeling.
The GPU algorithms developed in this work will complement NASA's combustion research. These new algorithms can be interfaced with NASA's in-house combustion CFD tools such as the National Combustion Code (NCC), to greatly facilitate modeling of combustion phenomena relevant for analysis of, for instance, gas-turbine engines. Specifically, NASA's capabilities for modeling emissions performance of gas turbine combustors, which requires incorporation of detailed combustion chemistry, will be greatly enhanced. Other NASA applications related to reacting flow simulations, such as rocket or aircraft propulsion or plume modeling, will also benefit from this project.","description":"We propose development of new algorithms specifically designed to exploit the highly parallel structure of graphics processing units (GPUs) for performing the following most expensive, but parallelizable computations in combustion CFD: (1) Chemical kinetics source term (including Jacobian matrix) evaluation; (2) Transport property evaluations; and (3) Matrix factorizations and inversions. The algorithms developed in this work will be implemented as software modules that can be easily interfaced with arbitrary CFD solvers for rapid computations using GPUs. A user guide will be delivered with directions for coupling the provided algorithms with users' CFD programs. Phase I work will demonstrate the computational acceleration achieved using the preliminary algorithms; and Phase II work will optimize the algorithms for improved performance and implement the algorithms as well-documented, distributable software modules as described above. This work will significantly increase the predictive capability of combustion CFD simulations by enabling efficient application of much larger chemistry models (which is essential, but currently prohibitively expensive) for accurately modeling the combustion of practical fuels.","startYear":2011,"startMonth":2,"endYear":2011,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":361125,"canUserEdit":false,"firstName":"Oluwayemisi","lastName":"Oluwole","fullName":"Oluwayemisi Oluwole","fullNameInverted":"Oluwole, Oluwayemisi","primaryEmail":"oluwoleo@aerodyne.com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":3164320,"canUserEdit":false,"firstName":"Anthony","lastName":"Iannetti","fullName":"Anthony Iannetti","fullNameInverted":"Iannetti, Anthony","primaryEmail":"Anthony.C.Iannetti@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":65464,"projectId":9657,"transitionDate":"2011-09-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"ppt","fileId":305677,"fileName":"SBIR_2010_1_FSC_A2.02-9607","fileSize":301056,"objectId":65464,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"294.0 KB"},"transitionId":65464,"fileId":305677}],"infoText":"Closed out","infoTextExtra":"","dateText":"September 2011"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
