摘要：
We consider a model of deposition of non reactive, adhesive micro-particles in a turbulent flow around a single short wall-bounded cylinder mimicking a segment of a plate-fin-and-tube heat exchanger. The flow field is provided by a prior LES (Borello et al. 2008) and the particles dispersion is described by the Particle Cloud Tracking of Baxter (1989). The deposition model is based on the balance between the rolling moments by the drag and the adhesion forces on the solid surfaces (Abd-Elhadi et al. 2004).
