Title:
Large Eddy Simulation of a particle-laden flow around a cylinder: Importance of thermal boundary layer effects for slagging and fouling 
Abstract:
This work presents a detailed and novel ash deposition model predicting early deposit formation validated with measurements conducted in a full-scale suspension fired boiler considering inertial impaction, eddy impaction, thermophoresis and condensation as deposition mechanisms. A cooled deposition probe, exposed for one week in the furnace region, is modeled using an isolated tube and Large Eddy Simulations. The flow field is validated against literature data using isothermal and non-is...    »
