Abstract
High fidelity, advanced multiphase models that capture details of the fuel-air interface evolution are essential to accurate prediction of fuel injection processes. Such simulations can lead to more accurate models or simulation capabilities to be used in design of aeroengine combustors and augmentors. In this SBIR program, CFDRC will develop a novel fuel injection atomization model by using an innovative multiphase approach, the Lattice Boltzmann Method (LBM). In Phase I, CFDRC''s existing multiphase LBM capability will be enhanced to improve numerical stability for realistic fuel-air density ratios in the aero-injectors and benchmarked against relevant test cases. A select case of jet breakup will be simulated and compared with existing data in the literature and CFDRC''s Volume of Fluid (VOF) prediction. In Phase I Option, the multiphase model will be parallelized and optimized for computational speedup. In Phase II, turbulence, thermal transport with phase change and wall interaction models will be implemented into LBM. The model predictions of jet atomization cases, including wall interaction, relevant to main combustor and augmentor fuel injection will be compared against measurements.
