説明
<p>The multi-physics and multi-scale simulation of thermal fluid - structure interaction on an oxy-fuel coal gasifier based on a large-eddy simulation of coal gasification and a heat conduction simulation on coal gasifier pressure vessel is described in this report. The LES employing the Eulerian-Lagrangian manner to describe the motion of coal particles was validated with comparing with the experimental data related to the semi-closed carbon capture system and it was revealed that the LES could quantitatively capture the feature of the coal gasification characteristics. Moreover, the LES coupled with the VOF method to simulate the motion of the high viscosity molten slag layer was also performed. This gas-solid-liquid three-phase reacting flow simulation is expected to be a reliable technique to optimize the gasification conditions for stabilizing the operation. The thermal fluid - structure interaction simulation strategy was developed precisely and its performance on the large-scale parallel computing was evaluated. The multi-phase and multi-scale simulation has a great potential as a digital twin to assess a practical-scale clean energy system.</p>
