Based on the present experimental observations and the known dendritic models, a numerical statistical model of primary dendritic spacing is first presented to the dendritic array in directional solidification at constant velocity. The numerical model is in good agreement with the experimental results. Key words:  directional solidification      primary dendritic spacing      stochastic simulation      Received:  18 May 1997      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1997/V33/I5/449 1 Han S H,Trivedi R.
