Optimization of 3D Smoke Simulation and Evaluation of Ventilation

The spread of smoke in fire situations is one of the most critical aspects of evacuation, and it is of great significance to study fire behavior. The realistic rendering of smoke simulation can be considered one of the most complex tasks in fluid dynamics of computer graphics. In this book, the proposed method of smoke simulation rendering is based on Fire Dynamic Simulator (FDS) from the output-result of Excel file, where the attributes of a dynamic particle (mass, position, velocity, forces, and life cycle) improved the efficiency, and the rendering was implemented by making smoke particles and motion effect. Thus, the proposed method can improve smoke simulation and particles more accurately and effectively. With the coordinates data from Excel file for DirectX particle system, it is changed the coordinate value of the particles, computed the moving location and finally the boundary of the smoke flow at mechanism simulation of fluid dynamics. In this proposed method, we focused on smoke location boundary, and this simulation code shows that the emission rate of 5000 particles, has performance improvement in computation time in up to 8% and gives reality to user’s view.
