Method of simulating nozzle spray interaction with fire, smoke and other aerosols and gases

摘要

A method is presented for calculating a force to apply to components in a computer simulation to simulate the effect that an extinguishing agent stream (e.g., water or foam from a nozzle) should have on airflow in the vicinity of the stream, thereby affecting the movement of other components of the simulation. The method is designed to work in real-time as part of a virtual reality, augmented reality, or other real-time 3-D graphics simulation. In addition to the preferred embodiment of calculating forces to apply to a fire and smoke plume, the invention also contemplates calculation of a force to apply to aerosols and particles that are not part of a fire and smoke plume.
