Large-Scale Numerical Analysis and Visualization of Combustion Flow-field in Aircraft Engine

The present paper introduces the visualization methodology of large-scale numerical analysis results of the atomization and the evaporation of fuel in the aircraft engine combustor. An analysis solver based on the VoF method is developed, and large-scale numerical analyses are conducted using 31.2 billion computational cells for the atomization analysis and 2.2 billion cells for the evaporation analysis. The analysis data is enormous on both analyses, and the costs of the visualization are over the CFD analysis cost in some cases. We achieve a smooth visualization environment with such large-scale data using in-situ visualization and conversion of three-dimensional data to iso-surface data.
