本研究的目的是通过引入考虑宾汉流体本构定律的双粘度模型，开发一种新的固-气-液相流三维数值模型“DOLPHIN-3D”。通过将模型应用于具有和不具有多个刚体的 Bingham 流体柱的塌陷问题来检验该模型的有效性。结果发现，该模型能够以适当的精度模拟宾汉流体的动态行为以及固-气-液相互作用。
The objective of the present study is to develop a new three-dimensional numerical model of solid-gas-liquid phase flow "DOLPHIN-3D" by introducing a bi-viscosity model considering the constitutive law of Bingham fluid. The validity of the model is examined by applying it to the collapse problems of a Bingham fluid column with and without multiple rigid bodies. As a result, it is found that the model is able to simulate the dynamic behavior of Bingham fluid as well as solid-gas-liquid interaction with appropriate accuracy.
