Axisymmetric lattice Boltzmann simulation of the heat-exchanger method-based sapphire crystal growth

•Axisymmetric solidification processes with the third kind of boundary conditions are simulated by modified 2D HLBM.•The established model demonstrates high accuracy over a large range of Biot and Stefan numbers.•The influences of dimensionless convective boundaries on HEM-based crystal growth syste...
