Mixing Milk and Honey: Simulating Miscible Fluid Dynamics with interMixingFoam in OpenFoam

How to use the interMixingFoam solver for miscible three-phase flow (milk, honey, air)
How to build a custom cup geometry with two inlets using blockMeshDict and parametric C++ macros
How to control time-based inlet behavior using groovyBC (e.g., milk enters 2 seconds after honey)
How to simulate initial fluid regions using setFields
Accurate definition of transport properties, including Newtonian viscosity, surface tension, and diffusivity
How to run parallel simulations using decomposePar and mpirun
How to visualize volume fractions, velocity, and pressure fields in ParaView
Comparing mesh resolutions (e.g., 20, 30, 40) and their impact on simulation accuracy

Description

Product Overview:

In this hands-on CFD tutorial, we simulate a real-world everyday scenario with strong engineering relevance: the mixing of milk and honey in a cup. Using OpenFOAM’s interMixingFoam solver, we investigate how fluids of very different viscosities interact in a multiphase, gravity-influenced system with air as the third component.

This tutorial emphasizes advanced OpenFOAM concepts including miscible multiphase flow, boundary control with groovyBC, setFields initialization, and accurate interface capture. It’s the perfect follow-up to the “Water Pushes Out Crude Oil” simulation.
