A comparative study of PCM melting process in a heat pipe-assisted LHTES unit enhanced with nanoparticles and metal foams by immersed boundary-lattice Boltzmann method at pore-scale
TL;DR: In this paper, the thermal conductivity of phase change materials (PCMs) is usually low which impedes the heat transfer efficiency in the LHTES system, adding high thermal conductivities nanoparticles or metal foams are the two common approaches to enhance the thermal performance of the PCMs.

Direct numerical simulation of coupled fluid flow and heat transfer for single particles and particle packings by a LBM-approach
Harald Kruggel-Emden,B. Kravets,M.K. Suryanarayana,Raimondas Jasevičius,Raimondas Jasevičius +4 more
TL;DR: In this paper, lattice Boltzmann methods (LBM) have been used to solve the Navier-Stokes equations for particle/fluid interaction. But the results of the results were not validated with available state-of-the-art correlations.

Discrete lattice effects on the forcing term in the lattice Boltzmann method
TL;DR: It is shown that discrete lattice effects must be considered in the introduction of a force into the lattice Boltzmann equation, and a representation of the forcing term is proposed that derived the Navier-Stokes equation through the Chapman-Enskog expansion.

Combined Immersed-Boundary Finite-Difference Methods for Three-Dimensional Complex Flow Simulations
TL;DR: In this paper, a second-order accurate, highly efficient method is developed for simulating unsteady three-dimensional incompressible flows in complex geometries, which is achieved by using boundary body forces that allow the imposition of the boundary conditions on a given surface not coinciding with the computational grid.

A Novel Thermal Model for the Lattice Boltzmann Method in Incompressible Limit
TL;DR: A novel lattice Boltzmann thermal model is proposed for studying thermohydrodynamics in incompressible limit that can incorporate viscous heat dissipation and compression work done by the pressure, in contrast to the passive-scalar-based thermal latticeboltzmann models.
