Multiphase flows occur when two or more fluids that are not mixed (such as air and water) find an interface. Multiphase flows can be categorized into single component multiphase fluids, e.g., water and vapor, and multi-component multiphase fluids such as oil-water mixture in porous media. These multiphase flow modeling methods that are divided into microscopic and macroscopic approaches have been the major focus of this review paper by emphasizing the methods of population balance model, level set, phase field, lattice Boltzmann, size exclusion, front-tracking, and volume of fluid. As a result of this study, it could be mentioned that the front-tracking and phase field methods could be accounted as methods with high accuracy and that the level set and volume of fluid methods are conceptually simple, while the phase field methods struggle with complex computational analysis. Achieving numerical instability like what happens to the lattice Boltzmann method is more probable than the phase field and volume of fluid method. Low computation time is the main advantage of the lattice Boltzmann method while the population balance method is suffering from a long time of analysis. Finally, appropriate methods must be selected based on the problem's concept, time, cost, and accuracy. In this study, a comparative study among various methods of multiphase flow modeling in porous media has been performed.
