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.
