A simulation tool to predict spontaneous aerosol formation in gas-liquid contact devices

Hamberger, Philipp; Schaber, Karlheinz; Piccioni Koch, Daniela

Abstract (englisch):
In gas-liquid contact devices like packed columns simultaneous heat and mass transfer take place and influence each other. Depending on the process conditions this can lead to a supersaturated state of the gas phase inside the device. When additionally solid particles are present, all perquisites for heterogeneous nucleation are fulfilled and aerosol formation can be observed (Schaber, 1995). The aerosol droplets are dispersed in the gas phase and are dragged along the device with the gas. When entering an undersaturated area inside or outside the device, the droplets evaporate again and thus have the potential to significantly influence the outcome of a process.
The simulation tool AerCoDe
The Institute for Thermodynamics and Refrigeration and the Steinbuch Centre for Computing at KIT are working on a simulation tool to model the heat and mass transfer in gas-liquid contact devices including the formation and growth of aerosol droplets. The model is based on the balance equations for mass and energy in the gas and liquid phase as well as in the aerosol droplets (Ehrig et. al., 2002). The separate phases are connected by heat and ... mehr
