A Ship Firefighting Training Simulator with Physics-Based Smoke

Under the current background of navigation education, students generally lack a comprehensive grasp of ship firefighting equipment's operation. Therefore, we develop a novel ship firefighting training simulator with a multi-sensory human-computer interaction function for teaching and training marine students. In the simulator, we consider a container ship of 1.8w containers as the prototype ship, and the entire ship models are built using three-dimensional modeling technology. We design various interactive modes and realize a full-process operation simulation of several standard ship firefighting equipment. Furthermore, we propose a purely Lagrangian vortex dynamics framework to simulate smoke and flame in fire scenarios. In this framework, we model fluids using velocity and vorticity fields discretized on discrete vortex segments. The main components of the framework include a stable geometric stretching solution and particle strength exchange method for solving the diffusion term. The simulation results show that the simulator has good behavioral realism and scene immersion and can be applied to ship firefighting training. To the best of our knowledge, this is the first study on real-time smoke simulation using a physics-based method in a firefighting training simulator.

Automated summary

In response to the lack of comprehensive understanding of ship firefighting equipment operation among marine students, we developed a ship firefighting training simulator. The simulator features multi-sensory human-computer interaction and utilizes three-dimensional modeling technology for ship models. We also proposed a new smoke simulation method to enhance the realism of training scenarios.
