abstract = {<p style="text-align: justify;">A new solver is developed to numerically simulate the melting phase change
with natural convection. This solver was implemented on a single Nvidia GPU based
on the CUDA technology in order to simulate the melting phase change in a 2D rectangular
enclosure. The Rayleigh number is of the order of magnitude of 10<sup>8</sup> and Prandlt
is 50. The hybrid thermal lattice Boltzmann method (HTLBM) is employed to simulate
the natural convection in the liquid phase, and the enthalpy formulation is used
to simulate the phase change aspect. The model is validated by experimental data and
published analytic results. The simulation results manifest a strong convection in the
melted phase and a different flow pattern from the reference results with low Rayleigh
number. In addition, the computational performance is estimated for single precision
arithmetic, and this solver yields 703.31MLUPS and 61.89GB/s device to device data
throughput on a Nvidia Tesla C2050 GPU.</p>},
