Fouling growth modeling of kraft recovery boiler fume ash deposits with dynamic meshes and a mechanistic sticking approach

0.7 μm diameter particles showed round and uniform deposits caused by thermophoresis. The deposit thickness grew up to about 3 mm after 100 min of fouling. 3.62 μm particle showed more irregular distributions with some high local peaks, but lower deposition rates in average. For this particular case modeled, the constant particle sticking probability approach showed no major differences with respect to the particle sticking submodel.
