Abstract:In this letter, a double multiple relaxation time (MRT) lattice Boltzmann method (LBM) based on double distribution lattice Boltzmann model is developed for numerical simulations of solid-liquid phase change. In contrast to previous lattice Boltzmann models, we solve the flow and temperature fields using the MRT-D2Q9 model and the MRT-D2Q5 model, respectively. The one-dimensional conduction melting and two-dimensional convection melting in a rectangular cavity for pure substance are investigated using the prop… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
