Abstract. Diffusion limited aggregation (DLA) is investigated in a Hele-Shaw cell with fluid flow. The morphology of the aggregation strongly depends on the flow. In general the patterns with low fractal dimension are obtained in the highest rate of flow, because the sticking to the aggregation occurs more often at the tip.
