About the Project
To cultivate research talents with global leadership, interdisciplinary innovation capabilities, and international research collaboration capabilities, Xi’an Jiaotong-Liverpool University (XJTLU) fully leverages its characteristics of international education and builds upon the long established strategic cooperation among XJTLU, Xi’an Jiaotong University (XJTU), and the University of Liverpool (UoL). This initiative integrates top-tier research resources to launch a Joint Doctoral Supervision…
Programme across the three institutions.
To address the complex coupling issues among inerting gas, fuel, and fuel tanks in aircraft fuel systems under high-angle-of-attack and large-overload conditions, a gasliquid-solid coupling mathematical model based on Smoothed Particle Hydrodynamics (SPH) was adopted to develop numerical tools for efficient numerical simulation analysis. Given that the coupled flow field solving capabilities of existing commercial fluid analysis software are constrained by the extremeness of flight conditions and the massive data in the solution space, the goal is to develop industrial software for analyzing, predicting, and regulating the inerting flow field in complex aircraft fuel tanks under different extreme high-dynamic service conditions.
The specific details are as follows:
- Research on deduction and prediction methods for multi-phase coupled flow field characteristics integrating momentum conservation constraints. Explore spatial eigenvalue extraction methods for fluid particle point clouds using convolution kernels to achieve step-by-step deduction of fluid particle positions and velocities over time scales. By combining anti-symmetric convolution kernels with momentum conservation constraints on fluid particle states, the computational accuracy and efficiency of data-driven simulation analysis solvers are enhanced.
- Development of simulation software for visualized analysis and regulation of three-dimensional flow field characteristics under extreme conditions. Develop solver-based prediction programs for multi-phase coupled flow field characteristics to achieve efficient solving of flow field characteristics under extreme conditions and environmental parameters. Design a 3D flow field characteristic cloud rendering engine and modular interface during the deduction and prediction process to enable high-quality human-machine interaction, data visualization, and performance analysis and evaluation.
