SPH原理、发展现状及热传导问题模型

Principle and status of technique of smoothed particle hydrodynamics and heat conduction model

对光滑粒子流体动力学方法(smoothed particle hydrodynamics,SPH)的基本技术原理及发展现状进行了综述,利用SPH方法对两个典型二维非线性动力学算例进行了数值模拟。同时,利用国外学者提出的方法初步探索了有关热传导问题的SPH模型。

The article is a summary about the basic theory and the developing status of technique of smoothed particle hydrodynamics （SPH）. Two typical examples of two dimensions nonlinear dynamics have been simulated numerically by SPH in the article. Otherwise, the SPH model on heat conduction problem has been discussed.
