Based on real nuclear explosions,a comprehensive explosion model is developed,which can achieve real-time simulation of nuclear explosion. Spherical expansion is adopted to express the shock wave,Additionally,fast collision detection is realized. The splash of the nuclear explosion is represented by using particle dispersion within the view range. The Navier-Stokes equations are simplified and solution strategies are optimized.Furthermore,the mushroom is realized with complex forms motion. Experimental results show that using the model can achieve a real-time simulation of the effects of a nuclear explosion. By controlling and adjusting the parameters,many different types of nuclear explosion effects can be obtained.
