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

“…Alternatively, this method can be used to simulate complex flow and transport phenomena especially in cases where direct solution of Navier-Stokes equations is not feasible (Martinez et al, 1994;Bouchut, 1999;Dellar, 2002). The LBM has already been successfully used in various fluid flow problems, such as multiphase and multicomponent fluid flows (Bao and Schaefer, 2012;Yan et al, 2011), thermal flow (Attar and Körner, 2011;Chen et al, 2012;Lin et al, 2012;Rong et al, 2010), flows through porous media (Rong et al, 2010;Hirabayashi et al, 2012;Boek and Venturoli, 2010), solid particle suspensions (Hirabayashi et al, 2012), non-Newtonian fluids (Chai et al, 2011;Ohta et al, 2011), reaction diffusion systems (Bresolin and Oliveira, 2012), and magneto-hydrodynamics, (Chen et al, 1991;Chen and Matthaeus, 1987;Chen et al 1988;Martinezet al, 1994;Bouchut, 1999;Dellar, 2002;2011;Kefayati et al, 2012).…”

In this study, the electrically conducting fluid flow inside a channel with local symmetric constrictions, in the presence of a uniform transverse magnetic field is investigated using Lattice Boltzmann Method (LBM). To simulate Magnetohydrodynamics (MHD) flow, the extended model of D2Q9 for MHD has been used. In this model, the magnetic induction equation is solved in a similar manner to hydrodynamic flow field which is easy for programming. This extended model has a capability of simultaneously solving both magnetic and hydrodynamic fields; so that, it is possible to simulate MHD flow for various magnetic Reynolds number (Rem). Moreover, the effects of Rem on the flow characteristics are investigated. It is observed that, an increase in Rem, while keeping the Hartman number (Ha) constant, can control the separation zone; furthermore, comparing to increasing Ha, it doesn't result in a significant pressure drop along the channel.

“…The D2Q9 lattice is used for solving flow field and the D2Q5 lattice is employed to compute energy field, similar with our previous work [15]. The LB scheme for fluid flow simulation and boundary treatment used in our previous work [15,16] is adopted here again. …”

In this paper a lattice Boltzmann (LB) model is proposed for conjugated heat transfer research. Through taking the most advantages of the standard LB method, the present model can remedy the shortcomings of the available related LB models via a simple way and meanwhile a number of intrinsic advantages of the standard LB method are preserved. It does not require any specific treatment dependent on interface topology and independent from the choice of lattice model. Moreover, it can be used for unsteady problems with complicated and time dependent interfaces. The accuracy and reliability of the present model are validated by three nontrivial benchmark tests. The good agreements between the present numerical prediction and available open data demonstrate the applicability of the present model for complicated conjugated heat transfer problems. Finally, the present model could be extended to some other important areas straightforwardly, such as fluid-solid phase change modeling.
