Hello, A change in allocation has been requested: Requester: ssom (Sibendu Som) Project: foam-EngineProcesses Title: Assessment of OpenFOAM for different Engine-Process Applications Description: The project is divided into two main parts: In the first part, fundamental studies will be performed to establish flame stabilization and lift-off characteristics of diesel and biodiesel. A new surrogate mixture (methyl decanoate + methyl decenoate + n-heptane) fuel will be used for modeling the combustion characteristics of biodiesel. The major motivation is to develop more predictive and robust sub-models for capturing diesel engine processes. Fairly large chemical-kinetic models, LES turbulence models, fine grid resolution facilitates use of more than one node (8 cores) for simulating these processes. In the second part, the engine full-cycle will be simulated and the effects of the computational grid on the predicted in-cylinder flow at the intake valve closing (IVC) will be analyzed. Furthermore, the mixture formation process of a gaseous fuel direct-injection will be studied. Here again, the use of computational grids characterized by very high resolution (as expected for the analysis of supersonic jets, jet-to-jet interaction and wall-jet impingement) will require parallel computing (1-2 nodes, 8-16 cores). Current: undetermined amount Justification: Requested: 90000 A specific reason has been given: Our usage was low in 2011 since we were not able to dedicate enough resources. From April we would be performing scalability studies with OpenFOAM and expect to use lot of core-hours. Also we are hiring a summer intern to work exclusive on OpenFOAM from May. This needs to be approved and the final allocation amount decided upon. Thank You, The LCRC Accounts System
