\n Multiphase flows with momentum, heat, and mass transfer exist widely in a variety of industrial applications. With the rapid development of numerical algorithms and computer capacity, advanced numerical simulation has become a promising tool in investigating multiphase transport problems. Immersed boundary (IB) method has recently emerged as such a popular interface capturing method for efficient simulations of multiphase flows, and significant achievements have been obtained. In this review, we attempt to give an overview of recent progresses on IB method for multiphase transport phenomena. Firstly, the governing equations, the basic ideas, and different boundary conditions for the IB methods are introduced. This is followed by numerical strategies, from which the IB methods are classified into two types, namely the artificial boundary method and the authentic boundary method. Discussions on the implementation of various boundary conditions at the interphase surface with momentum, heat, and mass transfer for different IB methods are then presented, together with a summary. Then, the state-of-the-art applications of IB methods to multiphase flows, including the isothermal flows, the heat transfer flows, and the mass transfer problems are outlined, with particular emphasis on the latter two topics. Finally, the conclusions and future challenges are identified.

Immersed boundary method for multiphase transport phenomena

One of the effective and economically viable methods in wastewater treatment is sorption, if for this sorbent, material of a natural, readily available origin is used, a material which can be effectively regenerated multiple times. Zeolites are natural or synthetic hydrated microporous aluminosilicates whose structure is characterized by the existence of the channel occupied by exchangeable cations and zeolite water. Due to their high cation exchange capacity, low cost, good thermal stability, and selectivity, which is based primarily on the fact that the channel dimensions determine which ions can enter and replace the naturally occurring cations, zeolites play a vital role among the sorbents for the removal of pollutants from the natural sources of water and wastewater. In order to completely understand the role of zeolites in the treatment of water, this paper discusses the structure of zeolites, some possible mechanisms for zeolite modification, the characterization of zeolites, and as a proposition for a sustainable process, consideration is given to the possibilities of the regeneration and reuse of zeolites in the process of water purification, while discussing the mechanisms of ion desorption. In order to address the problem of the resulting liquid waste after zeolite regeneration, the possibilities of using electrolysis with a dimensionally stable anode have been considered. The resorbed heavy metal ions from the zeolite could be concentrated by solvent extraction, and the metal ions would be returned by electrolysis to the production process, where pure cathode metals would be used in industry at the end of the cycle. In this way, the metal ions that pollute water are transformed into useful components that are economically viable. This paper outlines the most important characteristics of zeolites and modification options to make the most efficient use of the available zeolite and the desired result in the application of zeolites, to solve a specific problem of water treatment.
