Heat transfer process during the crystallization of benzil grown by the Bridgman–Stockbarger method

The temperature distribution and solid–liquid interface shape during benzil growth have been studied both experimentally and numerically. The heat transfer equation with appropriate boundary conditions has been solved by modelling a vertical Bridgman–Stockbarger growth configuration. Two models have been developed, namely a global numerical model and a pseudo-transient approximation in an ideal configuration.
