I suggest starting this project with 200k for Q3 and letting the allocations committee decide on Q4. Ray ----------------------------------------- Ray Bair Argonne National Laboratory On 4/21/16, 3:07 PM, "Zhang, Anqi" <[email protected]> wrote:
Ray,
Thanks for the email. Regarding the questions: 1) No, this project is neither part of a CRADA nor partnership with a company; 2) Yes, the results will be published in open literature.
Please let me know if further actions are needed. Regards, Anqi

Dear Anqi Zhang,
Thank you for the detailed project info. Is this project part of a CRADA or partnership with a company? Will the results be published in the open literature?
Regards,
Ray

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: Anqi Zhang Applicant's institution: ANL Applicant's division: ES Project Name: ignition-plasma Project title: Advanced Ignition Model Development Associated funding: DOE Vehicle Technologies Program Office Other Systems: Science: This project is dedicated to provide detailed descriptions of the complex ignition process involving thermodynamics, chemistry, fluid mechanics, and plasma science. Comprehensive and high-fidelity modeling of fuel-air mixture ignition by external energy source has become crucial for understanding the limit of high-efficiency internal combustion engine operations under lean and dilute conditions. This project will focus on characterizing the physical inputs of various ignition systems (conventional spark and non-thermal plasma systems) and assessing the quality of early flame kernel in terms of its capability to propagate. Project description: There are two major goals for this project: • Establish proper methodology to characterize different ignition systems and assess their effects on engine combustion • Investigate practical solutions to integrate essential physical processes to larger-scale engine simulations The numerical investigations will be carried out in the Eulerian domain, and the plasma will be simulated using one or both of the following approaches: 1) imposing initial chemical and thermodynamic conditions, and 2) expanding governing equations to account for electro-magnetic interactions. Experimental measurements of x-ray radiography (APS at Argonne National Laboratory), calorimetry (Sandia National Laboratories), and TALIF (two-photon laser induced fluorescence, Sandia National Laboratories) are available for model validation. Simulations will be performed using CONVERGE CFD code. The computational cell count is on the order of one to a few million cells depending on the physical geometries. Currently, there will be only one member user (zhanga) working regularly on this project performing on average 2 jobs daily. A typical job would require 48-96 cores, yielding an estimation of quarterly core-hrs requirement of 64 cores x 24 hrs x 90 days x 2 jobs = 276,480. In addition, I would also use some of the gpu queues for 3D numerical results processing to save the time transferring large files to local machines. Considering the queue time, I would request 225,000 core-hrs per quarter. Industry partnership: Project URL: Requested allocation: 450000 Q1: 0 Q2: 0 Q3: 225000 Q4: 225000 Justification: Storage requirements: I would like to request 3TB of disk storage for this project. The analysis of the simulation results highly relies on detailed post-processing of 3D numerical results. While comprehensive analysis often requires revisiting of multiple heavy datasets of high temporal resolution, I would like to keep large 3D output files for at least one month. A 3.5 million cell case could yield a 3D output file of 1GB at each time step, and it is desired to keep at least 100 time steps for such cases. Assuming on average one case to keep per day, the needed storage would be 1GB x 100 time steps x 1 case x 30 days = 3TB.
The requester has used undetermined amount hours of their initial startup project.
