Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Riccardo Scarcelli Project Name: FOA_dual_fuel Division: ES Project title: Efficiency-Optimized Dual Fuel Engine with In-Cylinder Gasoline/CNG Blending Associated funding: DOE - Office of Vehicle Technology Other Systems: Science: This project proposal, led by Argonne’s Center for Transportation Research, was submitted in response to the FY 2014 Vehicle Technologies Program Wide Funding Opportunity Announcement DE-FOA-0000991 (0991-1822) and was awarded with a total of $1,000,000 for FY2015, FY2016, and FY2017. Main goal of the project is to demonstrate that the proposed gasoline/CNG blending concept yields improved engine efficiencies over both gasoline and CNG-only operation by tailoring fuel properties based on engine load. 3D-CFD simulation plays a key role in carrying out fundamental analysis of the mixture formation process, with particular regard to the direct injection (DI) of natural gas within the cylinder, and in optimizing the engine operating parameters for a cost-effective engine design. Project description: This project focuses on investigating mixture formation and combustion in a single-cylinder engine fueled by port fuel injection of gasoline and direct injection of natural gas. To this aim, the numerical simulation of supersonic gaseous jets represent the main challenge from a CFD standpoint. At the current stage, the project has simulated mixture formation from DI of natural gas and has identified hardware modifications that can improve mixture formation and combustion, with a consequent benefit in terms of efficiency. This project will continue into FY2017, supporting engine hardware optimization as needed. CFD support will be provided by evaluating the effect of optimized configurations on engine performance. Simulations will be performed with the commercial code CONVERGE and computational grids of the order of some millions of cells will require the use of 32-64 cores. The project has one member and 2 jobs are expected to run on daily basis. With an average estimate of 48 cores per run and 2 cases in parallel, the expected amount of core-hrs needed for this project for each quarter is: 48 cores x 24 hrs x 90 days x 2 jobs = 207,000. Considering some queue time, our request is for 380,000 hrs total for the first two quarters. The effort will likely decrease later in FY2017, depending on how much support from CFD the experiments will require.
