Numerical modeling and simulation of particulate fouling on structured heat transfer surfaces using multiphase Eulerian-Lagrangian LES ( Dissertationsschrift )

Details ansehen

The application of structured heat transfer surfaces increase the local turbulence and thus thermal mixing. However, these structured surfaces are known to promote particulate fouling, hence the unwanted accumulation and deposition of suspended particles . The scope of this work is the development of a universal numerical CFD method for the prediction of particulate fouling. It can be shown that the usage of spherical dimples as surface structures is not only the optimal choice from a thermo-hydraulic point of view, but also favors a substantial reduction of particulate fouling.<eng>
