过饱和流体槽道流下粗糙壁上的析出会导致枝晶花纹的形成。溶质的被动平流对枝晶形态的影响与对流对过冷液体凝固枝晶的影响相似。结果表明，非对称枝晶生长依赖于溶质平流和湍流混合。文中还讨论了我们的研究对普通矿物鳞片形成现象的意义。
Precipitation on rough walls under a channel flow of a supersaturated fluid can lead to dendrite pattern formation. A passive advection of a solute has a great influence on the dendrite morphology similar to the convection effect on the solidification dendrites emerging from an undercooled liquid. We show how the asymmetric dendrite growth depends on the solute advection and turbulent mixing. Implications of our study on the generic mineral scale formation phenomena are also discussed.
