A -- HIGH REYNOLDS NUMBER TURBULENCE SOL BAA 98-025 DUE 100598 POC Techincal questions should be addressed by E-Mail only to warkc@onr.navy.mil BAA 98-025 The Office of Naval Research (ONR) is interested in receiving white papers addressing basic research in turbulence at high Reynolds number supporting Department of Navy interests in subsurface hydrodynamics. The overall goal is to increase our knowledge and understanding of the fundamental behavior of turbulence in high Reynolds number flows to improve capabilities of analyzing, predicting, and controlling turbulent flow around subsurface Naval platforms and weapons. Proposers are requested to focus on fundamental issues involving Reynolds number effects on turbulent wall-bounded flows and near-field wakes of constant density, single-phase, incompressible fluids. Topics include but are not limited to 2-D and 3-D boundary layers; 2-D and 3-D separation; vortex generation, evolution, and control; and complex flow interactions, such as 3-D boundary layers with embedded streamwise vortices. Effects of unsteady flow will be of interest in the third and following years and will be addressed undera follow-on BAA. Instrumentation needs are also of interest due to the higher spatial resolution requirements in high Reynolds number flows. Computational and theoretical efforts are also anticipated provided a clear link with possible experiments is outlined. Two facilities for experiments in high Reynolds number incompressible flow have been selected for use in this program: the Large Cavitation Channel (LCC) and the High Reynolds Number Testing Facility (HRTF). For a description of these facilities, please see WEB pages http://www50.dt.navy.mil/facilities/LCC.html and http://www.princeton.edu/~gasdyn/Facilities/Facilities.html#SuperTunne l. The characteristics of the facilities are quite different, and proposed investigations should take into account those differences. Since the HRTF is still under construction, efforts proposed for that facility should reflect that schedule; projects with a delayed start are possible. One test model (and possibly two) will be provided for each facility. For example, configurations could include: an axisymmetric body (supported by struts) with or without appendages such as control surfaces; a single large control surface; or attachments to these, such as fairings. Proposed configurations should reflect the fundamental issues being addressed by the proposal. It is expected that multiple simultaneous, or nearly simultaneous, investigations will be able to be performed on the selected models. Experiments will be conducted in the LCC for one to three weeks, once or twice per year, depending on project needs and available resources. Longer term experiments are envisioned for the HRTF, to be coordinated with facility development and in-house projects. The model configurations will be selected after reviewing the preliminary proposals. The investigators whose preliminary white papaers are judged appropriate to this BAA and to the selected configurations will then be notified of those configurations prior to preparation of the full proposals. Anticipated funding for fiscal year 1999 is $1M. Expected funding for the following four fiscal years is $2M, $2M, $2M, and $1M respectively, which are all subject to change. White papers are initially sought to preclude unwarranted effort on the part of an offeror in preparing a full proposal and are due 5 October 1998. Offerors submitting the most promising white papers will be invited to submit a full technical and cost proposal on all or part of their white paper submission. However, any such invitation does not assure a subsequent award. It is anticipated that several contracts, grants, cooperative agreements, or other transactions will be awarded under this announcement. This BAA announcement does not preclude an offeror from submitting a full technical and cost proposal or white paper after 5 October 1998. White papers and/or proposals received after 5 October 1998 may not be considered for funding under the Fiscal Year 1999 program. Submittals in response to this BAA are welcome until 30 November 1998. The Government reserves the right to select for award all, some, or none of the white paper submittals. White papers should include the following items: (A) Cover page, clearly labeled "White Paper", including BAA title and date, title, administrative and technical points of contact along with telephone, E-Mail address, and fax numbers, (B) Excluding the cover page, white papers are to be limited to seven pages, (C) White Papers shall consist of three primary sections: Technical, Managerial, and Cost. (D) The Technical section shall consist of clear descriptions of the research being proposed, objectives of the proposed effort, technical issues to be resolved to accomplish objectives, approach to resolving these issues, and specific prior experience of offeror in the technology areas being proposed. For proposed experiments, the model configuration must be described. For proposed computational and theoretical efforts, possible useful model configurations must be described together with tentative plans to utilize any appropriate experimental data for evaluating the research. The Management portion shall include key personnel, experience, facilities, and a plan of action. The Cost section shall include a one page cost breakdown of the effort being proposed, including needed travel to the proposed high Reynolds number facility. One page curriculum vitae for the Principal Investigator, and any other key personnel should be submitted. The vitae will not count toward the seven page limit. Four copies of the white papers are due at the submittal address listed below by 5 October 1998. White papers will be evaluated using the following criteria which are listed in descending order of importance: (1) Overall scientific merit; (2) Relevance to this High Reynolds Number Turbulence research program; (3) Qualifications and experience of the PI and other key research personnel; (4) Adequacy of facilities and equipment; (5) Budgetary cost and availability of funds. Offerors must state in their white paper that it is submitted in response to this BAA. Four hard copies of each white paper must be provided. White papers and full proposal submissions will be protected from unauthorized disclosure in accordance with FAR 15.413, applicable law, and DoD/DoN regulations. Proposed costs for a Government lab effort which are included as part of a team should be predicated on separate awards to the Government lab and the offeror. Government agencies will not be in direct competition with industry. The Standard Industrial Classification code is 8731 with the small business size standard not to exceed 500 employees. For awards made as contracts, evaluation of the socioeconomic merits will include the extent of commitment in providing meaningful subcontracting opportunities for small business, small disadvantaged businesses, woman-owned small business concerns, and historically black colleges and universities and minority institutions. Contract proposals that exceed $500,000 submitted by all but small businesses, must be accompanied by a Small, Small Disadvantaged and Women-Owned Small Business Subcontracting Plan in accordance with FAR 52.219-9. Total funding available for the five year duration of this BAA is estimated to be $8 million. This BAA provides no funding for white paper costs. It is expected that the Navy will make awards covering 12 to 36 month periods of performance through FY99. A subsequent BAA will be issued for the remaining three fiscal years. Unsuccessful offerors of white papers will be acknowledged. White papers will not be returned after evaluation. This CBD notice itself constitutes the BAA as contemplated by FAR 6.102(d)(2). Unless otherwise stated herein, neither additional written information is available, nor will a formal RFP or other solicitation regarding this announcement be issued. Requests for the same will be disregarded. No portion of this BAA has been set aside for HBCU and MI participants, though their participation is encouraged. White papers should be submitted by the due dates cited in the BAA to: Office of Naval Research, High Reynolds Number Turbulence BAA, ATTN: ONR Code 333 (CEW), BCT-1, Room 507, 800 N. Quincy Street, Arlington, VA 22217-5660. Technical questions should be addressed by E-Mail only to warkc@onr.navy.mil. The subject block of the E-Mail must contain "HRNTBAA" (only). Business questions regarding this BAA should be directed to: Office of Naval Research, Attention Terry Young (ONR 25), Room 720, Ballston Towers One, 800 N.
