20K looks fine to me, but the request may be too small. Ray ----------------------------------------- Ray Bair Argonne National Laboratory On 3/31/16, 3:59 PM, "[email protected] on behalf of [email protected]" <[email protected] on behalf of [email protected]> wrote:
Hello,
A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee.
Applicant's name: Dillon Shaver Applicant's institution: ANL Applicant's division: NE Project Name: CMFD-RANS Project title: Development of Multiphase RANS turbulence models Associated funding: NEAMS FSI Heat Exchanger LDRD Other Systems: Mira - shared project has ~25M CPU hours Science: The objective of this project is to develop and implement Unsteady Reynolds Averaged Navier-Stokes (uRANS) turbulence models in the Nek5000/Nek2P CFD code for use in multi-phase flow simulations. Project description: RANS and uRANS turbulence models are necessary for the accurate CFD simulation of flows on large scales, such as nuclear reactor fuel rod bundles and full cores. The current state-of-the art for simulation of boiling flows utilizes the RANS framework. Currently, a k-omega turbulence model has been demonstrated with Nek in the single-phase formulation. The goal of this project will be to extend that model to a multi-phase formulation. This will enable the further development and validation of multi-phase models with Nek and the subsequent simulation of large, complex problems of interest in both science and industry.
This project will use the CFD code Nek5000 and its branch, Nek2P. Written in a combination of Fortran and C, Nek has been demonstrated to be a highly scalable code using the MPI library. Nek5000 has a long history of use and development on the LCRC systems.
Proposed simulations will include helical pipe heat exchangers and nuclear reactor subchannel geometries. Meshes for these problems range in size from <100K elements to >1M elements. The project is expected to have between 2-4 members. Industry partnership: Project URL: Requested allocation: 20000 Q1: 0 Q2: 0 Q3: 10000 Q4: 10000 Justification: Storage requirements:
