After more than 3 decades developing modeling and computational methodologies for multiphase flow simulation, nowadays we have certain methodologies and tools for this purpose including: Eulerian-Eulerian, Eulerian-Lagrangian, Volume-of-Fluid (VOF), Smoothed Particle Hydrodynamics (SPH), Lattice Boltzmann Method (LBM), Discrete Element Method (DEM), etc. However to benefit from the available methods and tools, there is lack of basic CFD knowledge, and much more lack of experts who know basic concepts and modeling for Multiphase Simulations.
However most of the available positions and opportunities for CFD experts are related to multiphase flow simulations, not only in mechanical, material and process engineering but also for many new fields in pharmaceutical industry, biomedical, biotechnology, food process, environmental technology, mines and minerals, which are involve in multiphase phenomena, intensively. In comparison with CFD simulations of the single phase systems, we have to manage two additional following steps and required knowledge towards Multiphase Simulations:
1-Interface tracking/capturing algorithm (e.g. via definition of the phase indicator and interface reconstruction techniques in VOF)
2-Integrating surface forces term in Naiver-Stokes Equations at interface of two phases (e.g. via continuum surface force model in VOF).
And this is just the base for multiphase simulation for pure systems. Still there are other open challenges, such as:
-Concentration/Temperature dependence of Surface Tension values for most of the practical mixtures and solutions. In addition to the known surfactants & detergents, most of the petrochemical products, mines and minerals, food materials, drugs, micro-nanoparticles, dyes, pesticides, polymers, proteins, cells, microorganisms, are surface active. While small concentration of these material can be negligible on viscosity & density, it can change the Surface Tension and Interfacial Properties, dramatically, even in ppm levels.
-Additional functions and refinements for breakups and coalescence processes.
