No minimum or maximum; typical NSF awards range from $100,000–$500,000 over 3–5 years, but amounts vary by project scope.

Supports fundamental research on the transport of mass, momentum, energy, and species across scales, with broad applications in engineering and science.

--- ## Description The Transport Phenomena (TP) program funds fundamental research aimed at understanding, modeling, and controlling the transport of mass, momentum, energy, and species across multiple scales. The program welcomes proposals that use experimental, theoretical, or computational approaches and encourages innovative work that advances national priorities such as artificial intelligence, advanced manufacturing, biotechnology, microelectronics, energy, quantum science, and more. Research topics of interest include: - Dynamics of single- and multiphase systems (e.g., flow separation, turbulence, drag reduction, cavitation, instabilities, reactive flows) - Microscale–macroscale connections in fluid and material properties - Physicochemical phenomena at fluid-fluid and fluid-solid interfaces (e.g., adsorption/desorption, rheology, wetting, capillarity, electrokinetics, porous media, particle self-assembly) - Thermodynamics and thermal transport (e.g., conduction, diffusion, convection, phase transitions, radiation) in various systems - Combustion science, including chemical kinetics, turbulence-chemistry interactions, sustainable fuels, pollutant control, and diagnostics - Wildland fire behavior, including prevention, mitigation, and prediction at the wildland-urban interface The program encourages interdisciplinary and partnership-based research, including collaborations with federal agencies, industry, and international organizations. --- ## Due Dates - Proposals accepted anytime --- ## Funding Amount - No specified minimum or maximum award amount. - Most NSF awards in this area typically range from $100,000 to $500,000 total over 3–5 years, but actual amounts depend on project scope and budget justification. - No cost-sharing or matching required. --- ## Eligibility - Open to all applicant types ("Unrestricted"), including: - Academic institutions - Nonprofits - For-profit organizations - Government agencies - International organizations (subject to NSF policies) - Individuals may apply as principal investigators if affiliated with an eligible organization. --- ## Application Process - Proposals must be submitted via [Research.gov](https://www.research.gov) (not Grants.gov), following the NSF 24-1 Proposal & Award Policies & Procedures Guide (PAPPG). - Select Directorate for Engineering (ENG), Division of Chemical, Bioengineering, Environmental and Transport Systems (CBET), and the program name. - Follow all requirements in the [PAPPG](https://www.nsf.gov/policies/pappg/24-1). - Proposals are accepted on a rolling basis; there is no fixed deadline. --- ## Additional Information - All awards are subject to NSF’s updated [research security policies](https://www.nsf.gov/notices/important/important-notice-no-149-updates-nsf-research-security/in149). - For questions about program scope or fit, contact the TP Program Team (see below). - Browse recent [funded awards](https://www.nsf.gov/awardsearch/search-results?ProgEleCode=366Y00&BooleanElement=Any&BooleanRef=Any&ActiveAwards=true#results) for examples of supported projects. --- ## External Links - [NSF Program Description & Details](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=506550) - [Program Page on NSF.gov](https://www.nsf.gov/funding/opportunities/transport-phenomena) - [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1) - [Research.gov Submission Portal](https://www.research.gov) --- ## Contact Information | Contact | Email | |------------------------|-------------------------------| | TP Program Team | [cbet-tp@nsf.gov](mailto:cbet-tp@nsf.gov) | | NSF Grants.gov Support | [grantsgovsupport@nsf.gov](mailto:grantsgovsupport@nsf.gov) |
