Numerical Simulation of Dynamic Pressure Change in Transport Aircraft Cabin with Airdrop
Hangkong gongcheng jinzhan, 2021 When heavy equipment are airdropped, the cabin cross-section is largely blocked, and rapid moving of heavy equipment will cause drastic changes in cabin pressure and even damage the health of cabin crew.Therefore, it is necessary to carry out numerical ...

A parallel dynamic overset grid framework for immersed boundary methods
CoRR, 2019 A parallel dynamic overset framework has been developed for the curvilinear immersed boundary (overset-CURVIB) method to enable tackling a wide range of challenging flow problems. The dynamic overset grids are used to locally increase the grid resolution near complex immersed bodies, which are handled using a sharp interface immersed boundary method ...

Overset grids for fluid dynamics analysis of internal combustion engines
Energy Procedia, 2017 Abstract Overset grids is emerging as an increasingly important and powerful tool in fluid dynamics simulations. A model built with the overset mesh technique consists of multiple spatially superimposed grids, one for each moving element (valves and piston in case of internal combustion engines) plus one background grid (representing the fixed ...

Research on shock-vortex interaction of fairings based on dynamic unstructured overset grid
Journal of Physics: Conference Series, 2021 Abstract The fairing is used to protect the aircraft from aerodynamic heat and force at high-speed, while there exists strong shock-vortex interaction during fairing separation. The unsteady shock-vortex interaction is numerically studied based on dynamic unstructured overset grid in this paper, where the N-S equations and 6-DOF ...
