Data underlying the publication: Characteristics of slurry transport regimes: Insights from experiments and interface-resolved Direct Numerical Simulations

This data set contains all the data to produce the results of "Tariq Shajahan, Thijs Schouten, Shravan K.R. Raaghav, Cees van Rhee, Geert Keetels, Wim-Paul Breugem, Characteristics of slurry transport regimes: Insights from experiments and interface-resolved Direct Numerical Simulations, International Journal of Multiphase Flow, 2024, 104831, ISSN 0301-9322, https://doi.org/10.1016/j.ijmultiphaseflow.2024.104831". The flow problem was studied using a combination of experiments and Interface resolved Direct Numerical Simulations. The pipe geometry is implemented in the rectangular domain using a volume penalization method and periodic boundary conditions are applied at the ends of the pipe. The DNS is carried out rectangular domain filled with a viscous fluid in which immersed non-colloidal spherical particles are subjected to a crossflow along the pipe. The two phases in the simulation (fluid and particulate) are treated independently and coupled through a no-slip boundary condition enforced on the surface of the particle. The solution to the fluid phase is computed on a fixed Eulerian mesh and the moving surface of the particle is represented using a Lagrangian mesh that translates with the particle. The simulation code is developed in house and written in FORTRAN90. MATLAB, PYTHON and PARAVIEW has been used to generate the figures presented in the article.The Experimental data used for comparison is also included in the dataset.<br><br><br>

本数据集包含复现下述论文成果所需的全部数据：Tariq Shajahan、Thijs Schouten、Shravan K.R. Raaghav、Cees van Rhee、Geert Keetels、Wim-Paul Breugem，《浆料输运流态特性：实验与界面分辨直接数值模拟（Interface-resolved Direct Numerical Simulations）洞察》，《国际多相流杂志（International Journal of Multiphase Flow）》，2024年，文章编号104831，ISSN 0301-9322，DOI链接：https://doi.org/10.1016/j.ijmultiphaseflow.2024.104831。本研究结合实验与界面分辨直接数值模拟对该流动问题展开探究。管道几何结构通过体积惩罚法在矩形计算域中实现，并在管道两端施加周期性边界条件。本次直接数值模拟的计算域为充满粘性流体的矩形域，其中浸没的非胶体球形颗粒受到沿管道方向的横流作用。模拟中的两相（流体相与颗粒相）独立处理，并通过颗粒表面的无滑移边界条件实现耦合。流体相的控制方程基于固定欧拉网格求解，颗粒的运动表面则通过随颗粒同步平移的拉格朗日网格进行表征。本模拟代码为自研程序，采用FORTRAN90语言编写。论文中展示的所有图表均通过MATLAB、PYTHON与PARAVIEW生成。
