Abstract: Combining the unstable heat conduction in crystal layer with heat transfer of undeveloped slug flow in a vertical tube, a time-progression model of crystal layer growth in the bubble column crystallizer pipe is proposed, the calculation results from the numerical method agree well with the experimental data.Under certain operating conditions,the periodical arrival of gas plugs can cause crystallization and partial re-melting occur in the crystal-melt interface.
