A -- EVALUATION AND ANALYSIS OF MICROSCALE FLOW INSTABILITIES DURING REMEDIATION Sol. RFA-95-4. Due 042195. Contact Point, Stephen Kovash, (405) 436-8708. The USEPA, Robert S. Kerr Environmental Research Laboratory, in Ada, Oklahoma, is seeking assistance by cooperative agreement with non-profit organizatons (minimum of 5% cost sharing required) or by interagency agreement with Federal Agencies qualified to conduct theoretical and mathematical evaluation and analysis on fluid instabilities at the micropore scale during active aquifer remdeication with use of surfactants, cosolvents, air, and forms of energy. The required focus of the proposed project is on the development of conceptual, mathematical, and numerical and computional models which can predict the behavior of these remedial fluids at the micropore scale. Further, the recipient organization will verify the theoretical and coneceptual processes and evaluate the applicability of the concepts by comparision with data from laboratory experiments. The data will be made available through the cooperative research efforts with RSKERL scientists. The project is anticipated as a two-year project with the total cost of $210,000, pending availability of funds. Interested sources must request a solicitation package containing a scope of work, evaluation criteria, and additional instructions in writing before the response date of April 21, 1995. FAX requests may be directed to (405) 436-8597. Telephone requests for the solicitation package or technical information will not be accepted. (079)
