Hello, A change in allocation has been requested: Requester: ssom (Sibendu Som) Project: biodiesel-combustion Title: Computation Fluid Dynamics Modeling of Petrodiesel and Biodiesel Description: The project is dived in two parts: In the first part, engine processes will be modeled using petrodiesel. The spray data obtained from Advanced Photo Source at Argonne and single-cylinder engine performance and emission data from CAT cell will be used to further develop and validate spray and combustion models in CONVERGE and perform parametric studies. The major motivation is to develop more predictive and robust sub-models for capturing diesel engine processes. In the second part, fundamental studies will be performed to establish flame stabilization and lift-off characteristics of biodiesel using CONVERGE. A new surrogate (consisting of methyl decanoate, methyl 9 decenoate, n-heptane) fuel will be used for modeling the combustion characteristics of biodiesel. Comparison will be performed between inner nozzle flow, non-evaporating and evaporating spray, combustion characteristics, engine performance and emission characteristics of biodiesel and petrodiesel. B iodiesel fuel obtained from different feedstocks such as Soy, Cuphea, Rape-seed will be modeled. Blends of biodiesel with diesel fuel will also be simulated. The CONVERGE software has been observed to scale well up to 96 processors and full-cycle engine simulations. Current: undetermined amount Justification: Requested: 100000 A specific reason has been given: The allocation provided was lower than the original request during the allocation committee meeting. This needs to be approved and the final allocation amount decided upon. Thank You, The LCRC Accounts System
