摘要

Abstract

s Based on the theoretical foundations of lava-flow numerical simulation,we first review five classes of models—stochastic,1D channel flow,cellular automata,depth-averaged shallow water models,and 3D models—highlighting their underlying assumptions,computational efficiency,and applicable scenarios.Stochastic approaches deliver rapid run-times but supply no temporal evolution;1D channel models quickly quantify heat loss;cellular automata models balance high efficiency with simultaneous temperature and morphological data;depth averaged models are best suited to low-relief terrains;while 3D models provide the most complete dynamical and thermal information at the price of high computational cost.We conclude by outlining future directions:tighter constraints on lava rheology(viscosity and yield strength),more accurate representations of internal velocity and temperature fields,and the adoption of cutting-edge techniques from broader computational fluid dynamics.
