The theory of stable dendritic growth within a forced convective flow field is tested against the enthalpy method for a single-component nickel melt. The growth rate of dendritic tips and their tip diameter are plotted as functions of the melt undercooling using the theoretical model (stability criterion and undercooling balance condition) and computer simulations. The theory and computations are in good agreement for a broad range of fluid velocities. In addition, the dendrite tip diameter decreases, and its tip velocity increases with increasing fluid velocity.

具有强制对流的稳定树突生长：使用基于焓的建模方法的理论测试

在强制对流流场内稳定枝晶生长的理论与单组分镍熔体的焓法进行了测试。使用理论模型（稳定性准则和过冷平衡条件）和计算机模拟，将枝晶尖端的生长速率及其尖端直径绘制为熔体过冷度的函数。理论和计算对于广泛的流体速度非常一致。此外，枝晶尖端直径减小，其尖端速度随着流体速度的增加而增加。
