NUMERICAL SIMULATION ON AIRBORNE SUBSTANCES OF BLASTING VOLCANIC ERUPTION
爆破性火山喷发空降物的数值模拟

Suzuki 2D diffusion model is modified and used to simulate the distribution characteristics of volcanic eruptive clastic sediment at Tianchi,Changbaishan. Furthermore,the influences of height of eruption column and wind velocity on the distribution of sediment are discussed. This simulation is useful in hazard prevention or evaluation of disaster in regions of volcanic activity or regions of potential volcanic activities. It is also meaningful for environment protection.
