- Description
- Request for Information (RFI) DARPA-SN-23-63 Measuring, Modeling, and Manipulating the Turbulent Boundary Layer Responses Accepted: Until 4:00 p.m. (Eastern) on June 27, 2023� Point of Contact: Susan Swithenbank, Program Manager, DARPA/DSO Email Address: DARPA-SN-23-63@darpa.mil �� The Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office (DSO) is requesting information regarding (1) ways to measure, visualize, and model the high Reynolds number turbulent boundary layer and (2) information on development of technologies to reduce turbulent pressure fluctuations and their influence on the underlying structure. � REQUESTED INFORMATION This RFI seeks responses that address the following key challenges: Measurement: Measurement capabilities for turbulent boundary layer flow fields that improve on the state of the art for various flow surface configurations at high Reynolds number conditions including: individual sensors and arrays for improved resolution of low-wavenumber surface pressure fluctuations sensing capability for the measurement of the fluctuating surface shear stresses in both the streamwise and spanwise directions measurements of the near-wall velocity field with sufficient spatio-temporal resolution to inform and advance understanding of physical mechanisms in the flow field Manipulation: Surface configurations designed with the intent to: delay laminar-to-turbulent transition. Delayed transition would imply less turbulent flow on a structure, thus, less overall unsteady fluid structure interaction. realize methods that yield reduced mean surface shear. Surface configuration assessments are needed to understand if reductions in mean surface shear will translate to beneficial characteristics of the unsteady surface pressures and unsteady shear stresses. modify the wavenumber of or reduce the energy in the turbulent eddies and shear flows near the wall-bounded surfaces, which may offer a means to reduce the unsteady fluid-structure interaction. Modeling: Spatio-temporal high Reynolds number turbulent flow modeling capabilities validated using experimental data to accurately model the effects of the flow manipulations WORKSHOP A DARPA-sponsored workshop is being planned for July 27, 2023, in Arlington, VA, for the purpose of reviewing and discussing current and future research relevant to this RFI, addressing new insights and challenges in this area, and providing an opportunity for different communities (academia, industry, government) to share their capabilities and ideas for future teaming arrangements in anticipation of subsequent solicitations that may be issued in this or related areas.� In addition, information discussed at this workshop may assist in the formulation of possible future areas of DARPA research with the objective of understanding and manipulating turbulent flow structural interactions. Workshop space is limited and only RFI respondents will be eligible to attend. Respondents who cannot attend the workshop in person will have the option to attend virtually. Responses to this RFI must be received by DARPA no later than 4:00 p.m. (Eastern), June 27, 2023.� Some individuals will be asked to make formal presentations. Formal presentations are expected to be approximately 20 minutes in duration, and presentation materials should be limited to non-proprietary and publicly releasable information. The workshop format will be a combination of group discussion and formal presentations. DARPA will determine the list of formal presentations based on RFI submissions. Invitations will be sent via email by 12:00 p.m. (Eastern) on July 7, 2023 and will provide further details on the workshop.� All attendees, virtual or in person, including those who will not be giving presentations, will be encouraged to participate in general discussions and to make recommendations for future research in the area. Invitations to the workshop will be issued to selected formal presenters first. Other RFI respondents will be invited on a first-come, first-served, space available basis, based on RFI response date and time. Attendance will be limited to virtual participation once the in-person capacity has been reached. Attendees will be limited to no more than two (2) individuals per CAGE (Commercial and Government Entity) Code. Invitees who are not U.S. citizens and wish to participate will need to complete and submit either a DARPA Form 60 (U.S. Permanent Resident and Foreign National Visit Request � e.g., industry or academia) or an Official Visit Request (foreign government personnel, only) through their government�s Embassy, no later than 4:00 p.m. (Eastern), July 21, 2023. DARPA Form 60 submission instructions are provided on the registration website. Contact your Embassy staff for assistance in submitting the Official Visit Request. SUBMISSION FORMAT Respondents to this RFI are encouraged to be as succinct as possible, while also providing actionable insight. �Page limits for each section are indicated below.� Format specifications for responses include 11-point font, single-spaced, single-sided, 8.5 by 11-inch paper, with 1-inch margins in MS Word or Adobe PDF format. � To the maximum extent possible, respondents are encouraged to send non-proprietary information. Respondents are responsible for clearly identifying any page conveying proprietary information with a label such as �Proprietary� or �Company Proprietary.�� DO NOT INCLUDE ANY CLASSIFIED INFORMATION IN THE RFI RESPONSE. Cover Sheet (1 page): Provide the following information. Response Title Technical point of contact name, organization, telephone number, and email address Indicate the RFI challenge(s) addressed by the response Technical Description (no more than 5 pages). Graphics within the technical descriptions are encouraged to the extent that they aid in succinctly describing the concepts. Bibliography/References (no more than 2 pages) Graphic Overview Slide (Optional): If desired, include a single PowerPoint slide that graphically depicts the main ideas of the response.� SUBMISSION INSTRUCTIONS AND CONTACT INFORMATION All responses to this RFI must be emailed to DARPA-SN-23-63@darpa.mil. �Responses will be accepted any time from the publication of this RFI until 4:00 p.m. (Eastern) on June 27, 2023.� Early responses are encouraged. All technical and administrative correspondence and questions regarding this RFI should also be sent to the same email address. Emails sent directly to the DARPA Program Manager may result in a delayed or no response. ELIGIBILITY DARPA invites participation from all those engaged in related research activities and appreciates responses from all capable and qualified sources, including, but not limited to, universities, university-affiliated research centers (UARCs), Federally-Funded Research and Development Centers (FFRDCs), private or public companies, and Government research laboratories. DISCLAIMERS AND IMPORTANT NOTES This is an RFI issued solely for information and new program planning purposes; it does not constitute a formal solicitation for proposals. In accordance with Federal Acquisition Regulation 15.201(e), responses to this RFI are not offers and cannot be accepted by the Government as such.� Responses do not bind DARPA to any further actions related to this topic, including requesting follow-on proposals from respondents to this RFI.� Submission is voluntary and is not required to propose to a subsequent Broad Agency Announcement (if any) or other research solicitations (if any) on this topic.� DARPA will not provide reimbursement for costs incurred in responding to this RFI or for travel costs to attend the event in person.� Respondents are advised that DARPA is under no obligation to acknowledge receipt of the information received or provide feedback to respondents with respect to any information submitted under this RFI. DARPA will disclose submission contents only for the purpose of review. Submissions may be reviewed by the Government (DARPA and other Government partners); FFRDCs; and Scientific, Engineering and Technical Assistance (SETA) support contractors.
