A -- DEVELOPE AND VALIDATE A NUMERICAL MODEL FOR PREDICTING THE PERFORMANCE OF A SHEAR ROLL MILL DUE 021200 POC Mr. Ed Krajkowski (973)724-3239 WEB: US ARMY TACOM-ARDEC Procurement Network, http://procnet.pica.army.mil/cbd/SRCSgt/011320000/011320000.htm. E-MAIL: Ed Krajkowski, ekrajkow@pica.army.mil. TACOM-ARDEC seeks to develope a numerical model for predicting the performance of a shear roll mill (SRM). The model must be sufficiently robust to make predictions of SRM performance at several sizes (200-mm, 300-mm) when processing various propellent formulations (TBD).The model shall be validated by processing both inert simulants and energetic materials on a 200-mm SRM. TACOM-ARDEC shall make provisions for validation of the model using a 200-mm SRM at Radford AAP, Blacksburg, Va. The purpose of this survey is to identify contractors having the capability to develop and validate such a numerical model of the SRM. At a minimum, they should be able to demonstrate the following: Experience in handling energetic materials, Ability to develope simulants, Ability to specify control equipment to be installed on the SRM fordata acquisition (transducers, etc),Expertise in designing experiments to validate theoretical model in terms of both mechanical (flow dynamics) and thermal processes which are occurring. Ability to characterize the rheological behavior (including wall slip) behavior of energetic materials and simulants, Proven capabilities in mathematical modeling and the implementation of numerical methods particularly with viscoplastic material subject to wall slip, Posses sufficiently fast computers to run the model within time frames comparable to the relevent industrial operation, Facility suitable for continuously addressing the needs of the Army to run the mathematical model at relatively short intervals to gain the targeted benefits from this modeling effort.
