| Title: Non-dimensional Lattice Boltzmann Simulations for Thermal Energy Transportation in Porous Media | |
| Abstract: Full system pore scale simulations of the thermal energy transport in porous mediums are challenge problems for high performance computation (HPC), because extreme large computational costs are necessary due to the multiple space and time scales. Recent mesoscopic length scale based Lattice Boltzmann Methods (LBMs) provide a powerful tool for advances of solving the multi-scale problem due to the advantage of considerably faster computational speeds comparing to conventional numerical methods, which are governed by the macroscopic length scale Navier–Stokes and thermal energy transport equations. The non-dimensional lattice Boltzamann method (NDLBM) developed from the conventional LBMs by directly applying the mesoscopic dimensionless governing parameters, which clarified the relationships between the macroscopic and mesoscopic scales. The dimensionless collision relaxation times expressed by the dimensionless governing parameters simplified the applications of the NDLBM. Key bridges between the mesoscopic and macroscopic transport are given. Parallelization NDLBM schemes for effective computation and communication for HPC are shown. The present uniform form module based NDLBM based scheme are expected to solve various coupled problems on heat transfer and thermophysics. Application examples for thermal energy transportation will be illustrated based on the recent results in various application fields, such as thermal conduction in various microscopic structures, diffusion through ventilation systems, natural convection through three dimensional fiber structures, and discontinuous phonon energy transportation. | |
