摘要

摘要这项工作提出了一种在动态自适应八叉树网格上模拟自由表面非牛顿（粘塑性或粘弹性）流体流动的新方法。该数值模型基于隐式公式和控制变量的交错位置。我们通过将模拟结果与文献中已知的实验和数值结果进行比较来验证我们的模型。

An implicit scheme for simulation of free surface non-Newtonian fluid flows on dynamically adapted grids

Abstract This work presents a new approach to modelling of free surface non-Newtonian (viscoplastic or viscoelastic) fluid flows on dynamically adapted octree grids. The numerical model is based on the implicit formulation and the staggered location of governing variables. We verify our model by comparing simulations with experimental and numerical results known from the literature.
