ABSTRACT: Recently, smoothed particle hydrodynamics (SPH) method
has become popular in computational fluid dynamic and heat transfer simulation.
The simplicity offered by this method made some complex system in physics such
as moving interface in multiphase flow, heat conductivity jumping in multiple
material boundaries and many geometrical difficulties become relative easy to
calculate. We will treat a relative easy example of melting process to
test the method in solving fluid motion equation coupled by heat transfer
process. The main heat transfer processes are caused by solid-liquid (medium to
medium) heat diffusion and convection. System interaction with ambient
temperature can be modeled by gas surrounding fluid-solid system. For the
ambient temperature, we proposed surface particle heat transfer governed by
convectional heat flux. Using local particle number density value as surface
detection method, we applied cooling and heating to surface particle on the melting
ice cube and water system. The simulation result is also verified by
experiment.
