HETEROGENEOUS CONDENSATION FOR SUBMICRONIC PARTICLE ABATEMENT: EXPERIMENTS AND MODELLING

This paper reports a study of the heterogeneous condensation of sub-micrometric particles produced by a model ethylene/air flame, performed with an instrumented lab-scale plant. Tests were performed by varying the temperature of the condensing vapour and the gas residence time. Experiments can be described by using consolidated models for heterogeneous condensation, provided that the contact angle is considered as an adjustable parameter, variable with temperature
