Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Sibendu Som Project Name: foam-EngineProcesses Division: ES Project title: Assessment of OpenFOAM for different Engine-Process Applications Associated funding: DOE-Vehicle Technologies Office Other Systems: Science: This project will use an Eulerian-Lagrangian Computation Fluid Dynamics (CFD) open source code called OpenFOAM to model various internal combustion engine processes like engine full-cycle and gas-exchange, sprays and gaseous jets behavior, nozzle internal flow, mixture formation, combustion and exhaust emissions. The goal is to assess the performance of OpenFOAM for varied engine-process applications. Scalability of OpenFOAM for different applications will also be tested. Project description: This year there will be three major focus areas for this project: 1) Spray combustion simulations will be performed to assess the Eulerian-Lagrangian spray models and detailed combustion models in OpenFOAM. The 3D turbulent spray combustion simulations will be performed with n-heptane as a surrogate to diesel fuel. The experimental data was obtained from Sandia National Laboratory for liquid length, vapor penetration, ignition delay, and flame lift-off lengths. The predictive capability of OpenFOAM for engine relevant problems will be assessed. 2) Results with OpenFOAM will be compared against simulations with a commercially available engine modeling software called CONVERGE. CONVERGE software is known to be well calibrated against experimental data under the range of conditions of interest for the PI. Special care will be taken to ensure that the model set-up, grid-size, boundary conditions, numerical schemes implemented are consistent between the two codes. 3) A visiting scholar from Politecnico di Milano is expected to join our team in January 2014. The focus of his research will be to assess grid related issues with OpenFOAM. Specifically he will be identifying Project URL: http://www.transportation.anl.gov/engines/multi_dim_model_home.html Current FY Hours Used: undetermined amount New FY Requested allocation: 499000 Q1: 125000 Q2: 125000 Q3: 125000 Q4: 124000 Justification: Thank You, The LCRC Accounts System
