“…In their study, the free convection flow through an annulus packed with porous media and natural convection in a closed cylindrical annulus filled with porous media were modeled. Later, Rong et al [289] studied heat transfer enhancement in a pipe filled with porous media by using their axisymmetric DDF-LB model based on the graphics processing unit (GPU). As shown in Fig.…”

Since its introduction 30 years ago, the lattice Boltzmann (LB) method has achieved great success in simulating fluid flows and modeling physics in fluids. Owing to its kinetic nature, the LB method has the capability to incorporate the essential microscopic or mesoscopic physics, and it is particularly successful in modeling transport phenomena involving complex boundaries and interfacial dynamics.The LB method can be considered to be an efficient numerical tool for fluid flow and heat transfer in porous media. Moreover, since the LB method is inherently transient, it is especially useful for investigating transient solid-liquid phase-change processes wherein the interfacial behaviors are very important. In this article, a comprehensive review of the LB methods for single-phase and solid-liquid phase-change heat transfer in porous media at both the pore scale and representative elementary volume (REV) scale. The review first introduces the fundamentals of the LB method for fluid flow and heat transfer. Then the REV-scale LB method for fluid flow and single-phase heat transfer in porous media, and the LB method for solid-liquid phase-change heat transfer, are described. Some applications 2 of the LB methods for single-phase and solid-liquid phase-change heat transfer in porous media are provided. In addition, applications of the LB method to predict effective thermal conductivity of porous materials are also provided. Finally, further developments of the LB method in the related areas are discussed. Keyword: Lattice Boltzmann method; Single-phase heat transfer; Solid-liquid phase change; Porous media proposed the RLBE model with an enhanced collision operator, which was shown to be linearly stable. Based on the Bhatnagar-Gross-Krook (BGK) collision operator [104], the LB model using a single relaxation time, referred to as the BGK-LB model, has been independently proposed by Chen et al. [14], Koelman [15], and Qian et al. [16]. In the BGK-LB model, the equilibrium distribution function is chosen to recover the incompressible N-S equations in the incompressible limit. Due to its high efficiency and extreme simplicity, the BGK-LB model has become the most popular LB model, in spite of some well-known deficiencies (e.g., numerical instability, viscosity dependence of boundary 9 locations). Almost at the same time when the BGK-LB method was developed, d'Humières [17] proposed the multiple-relaxation-time (MRT) LB method. The MRT-LB equation (also referred to as generalized lattice Boltzmann equation (GLBE)) is an important extension of the RLBE proposed by Higuera et al. [12,13]. This work is significant because, in addition to it overcomes some deficiencies of the BGK-LB model, it facilitates the extension of the LB method, expanding the applications to a much wider range of phenomena and processes.In 1997, a direct connection between the LB equation and the continuous Boltzmann equation in kinetic theory was rigorously established by He and Luo [19,20]. In particular, it has been demonstrated that the LB equation c...

“…They utilized the finite difference Crank-Nicolson scheme and the local one-dimensional approach for the model formulation intended for the use on GPUs. Rong et al (2014) developed a three-dimensional parallel heat transfer model for the calculation of fluid flow and heat transfer characteristics in a pipe with embedded porous media. Ansoni et al (2015) investigated the acceleration of the inverse heat transfer problem by means of parallel computing with the use of GPUs and multi-core CPUs.…”

“…A cylindrical vessel packed with solid desiccant particles represents a simple case of a pipe with porous media insert 10 . For a duct partially filled with porous media, forced convection is found to potentially enhance the heat transfer rate with the pressure drop much less than that of a duct fully filled with porous medium 11,12 .…”

Three packed beds of solid desiccants with different configurations have been modelled and simulated under forced convection in subsonic flow regime. The beds were of varied lengths but their collective porous sections and other parameters were similar. The simulation was carried out using the thermal equilibrium porous jump model in ANSYS Fluent and solutions computed using the density based coupled implicit solver. The results show wall heat transfer parameters to be relatively high around porous media insert for all three configurations. It is also demonstrated that narrowing the clear fluid section between porous insert impacts on the flow behaviour and the thermal enhancement of the bed. Flow behaviour for all three packed bed configurations was found to be significantly different in the three configurations.
