“…Nevertheless, we should keep Eq. (20) in mind in some cases, e.g., in the case of calculating the strain rate tensor using the second-order moment of the non-equilibrium distribution function, which is often required in the LB simulations of non-Newtonian flows [154][155][156][157] and in the LB-based simulations of turbulent flows [158,159]. According to the Chapman-Enskog analysis of the standard LB-BGK equation, namely Eq.…”

Over the past few decades, tremendous progress has been made in the development of particle-based discrete simulation methods versus the conventional continuum-based methods. In particular, the lattice Boltzmann (LB) method has evolved from a theoretical novelty to a ubiquitous, versatile and powerful computational methodology for both fundamental research and engineering applications. It is a kinetic-based mesoscopic approach that bridges the microscales and macroscales, which offers distinctive advantages in simulation fidelity and computational efficiency. Applications of the LB method are now found in a wide range of disciplines including physics, chemistry, materials, biomedicine and various branches of engineering. The present work provides a comprehensive review of the LB method for thermofluids and energy applications, focusing on multiphase flows, thermal flows and thermal multiphase flows with phase change. The review first covers the theoretical framework of the LB method, revealing certain inconsistencies and defects as well as common features of multiphase and thermal LB models. Recent developments in improving the thermodynamic and hydrodynamic consistency, reducing spurious currents, enhancing the numerical stability, etc., are highlighted. These efforts have put the LB method on a firmer theoretical foundation with enhanced LB models that can achieve larger liquid-gas density ratio, higher Reynolds number and flexible surface tension. Examples of applications are provided in fuel cells and batteries, droplet collision, boiling heat transfer and evaporation, and energy storage. Finally, further developments and future prospect of the LB method are outlined for thermofluids and energy applications.3

“…In these cases the rheological behaviour of the fluid must be taken into account (Cho et al, 2015). Electro-osmotically driven non-Newtonian flow in a porous medium was studied by Tang et al (2010) through a LBM based on the REV scale. To simulate the fluid flow in porous media they adopted the generalised model proposed by Nithiarasu et al (1997): they implemented two source terms, one to take into account the flow resistance for Non Newtonian fluids flowing in porous media (Herschel and Bulkley, 1926;Al-Fariss and Pinder, 1987), and the other to consider the electro-osmotic effect.…”

Purpose This paper aims to provide a comprehensive literature review on modelling electro-osmotic flow in porous media. Design/methodology/approach Modelling electro-osmosis in fluid systems without solid particles has been first introduced. Then, after a brief description of the existing approaches for porous media modelling, electro-osmotic flow in porous media has been considered by analysing the main contributions to the development of this topic. Findings The analysis of literature has highlighted the absence of a universal model to analyse electro-osmosis in porous media, whereas many different methods and assumptions are used. Originality/value For the first time, the existing approaches for modelling electro-osmotic flow in porous have been collected and analysed to provide detailed indications for future works concerning this topic.

“…Wang et al 12 examined the mixing process in microchannels via the simulation of 2D electrokinetically driven°ow, where the microchannel is populated with patterned blocks. Tang et al 13 numerically analyzed the non-Newtonian°uid for EOFs in microchannels. Wang and Kang 14 presented a coupled lattice Boltzmann scheme for modeling the electrokinetic°ows in microchannels to determine the conditions, where Poisson-Boltzmann equation is valid.…”

Motivated by the growing interest in electroosmotic°ows (EOFs) as a reliable no moving parts strategy to control°uid motion in various micro°uidics, two-dimensional (2D) steady-state EOFs in the presence of a charged mid-plate have been numerically investigated. A variation of lattice Boltzmann models is used to recover all governing equations, where the Nernst-Planck equation is employed to model the internal electrical¯eld. Results are validated by comparing the velocity pro¯les in the 2D uniform EOFs against their analytical solutions. The numerical results show that the velocity pro¯le and volumetric°ow rate are strongly in°uenced by the ratio of the electrical double layer (EDL) thickness to the channel height. In addition, the e®ects of positioning and thickness of the charged mid-plate on the electric¯eld distribution, velocity pro¯le and°ow rate are examined in detail.
