A lattice Boltzmann model for frost crystal growth on a cold flat surface
The lattice Boltzmann method(LBM)has become a particularly successful scheme to simulate the flow involving interfacial dynamics and complex boundaries due to its high accuracy,simple algorithm and easiness to handle boundary conditions.Frost crystal growth is a very complex process with transient heat and mass transfer.Due to the porous characteristics of the frost crystal,this paper proposes a 2D lattice Boltzmann model to simulate the frost crystal growth process on a cold flat surface.Based on actual frost crystal growth details,this simulation is concerned with the spatial variation of the frost thickness and mass increase.Some important results are obtained such as the temperature field of frost crystals.The predicted results are found to be in good agreement with the data reported in the literatures.
