Abstract

The study presented a simulation of non-Fourier heat conduction with phase change using a hyperbolic lattice Boltzmann method (HLBM). To handle the latent-heat source term, the equilibrium distribution function was modified for the temperature, leading to a novel approach. Unlike the conventional lattice Boltzmann method (LBM), the HLBM process employed a hyperbolic collision operator. This innovative approach facilitated the retrieval of the enthalpy conservation equation without the need for iteration stages or solving groups of linear equations. Consequently, this method demonstrated enhanced efficiency and accuracy compared to previous approaches. The research showcased the potential of employing HLBM in simulating intricate thermal processes, especially those involving phase change. The approach’s applicability extends to various domains, including designing efficient heat exchangers and gaining insights into material behavior during phase transitions. The findings suggest that HLBM holds promise as a valuable tool for addressing complex thermal phenomena and advancing our understanding of such processes.
