Modeling Butanol Blended Fuels for CI Engines
Combustion of fossil fuel for energy and transportation purposes is believed to be one of the most important causes of large-scale environmental pollution. Different types of alternative fuels are being investigated to replace these fossil fuels. One of the more recent alternative fuels that has attracted the attention of the research community is butanol, due to its favorable thermophysical properties. This webinar discusses the development and validation of an n-dodecane/n-butanol/NOx/PAH reaction mechanism consisting of 246 species and 1,062 reactions, as simulated using Ansys Chemkin Pro. This mechanism was validated using ignition and species data from the open literature. Subsequently, the mechanism was coupled in Ansys Fluent to simulate turbulent combustion dynamics inside a compression ignition engine. Liquid spray combustion was simulated using a coupled Eulerian-Lagrangian approach. We also used the KHRT droplet breakup model, the standard k-ε turbulence model and the unsteady flamelet model to simulate combustion chemistry and turbulence interaction. The liquid spray combustion model was validated using ECN Spray A data. Subsequently, a parametric study was performed to understand the effect of engine operating conditions on NOx and soot emissions. This webinar considers the effects of various parameters on engine performance, like the injection pressure, the start of injection and split injection for various n-butanol blend ratios.
Intel Processor Selection for Ansys Mechanical and Fluent Workloads
Selecting the correct Intel processor family and processor model number to run Ansys Fluent and Ansys Mechanical workloads is a critical design decision that directly impacts the costs and benefits of computer aided engineering (CAE) efforts. To assist customers, Intel collaborated with Ansys and with MVConcept to measure the performance of select Intel Xeon Scalable processor families using both single and multi-node Ansys Fluent and Ansys Mechanical official benchmarks spanning a range of size regimes and solvers. The performance results reflect the complex relationship between computational efficiency, processor core count, core frequency and memory bandwidth.
