| 摘 要： | Motivated by the need for three-dimensional methods for interface calculations we describe a 3D non-conservative difference scheme in Lagrange coordinates for calculating multi-component fluid dynamics, according to the thoughts of 2D non-conservative difference scheme and making use of difference method of characteristic and Upwind form. Furthermore, we give a three-dimensional numerical simulation of explosion in concrete, and the results of simulation are consistent with examination.
