In the first funding period, a heteroaggregation process was developed through desublimation in a supersonic flow (both homogeneous and heterogeneous). In the second funding period of the project, a multiscale model of aggregate formation and growth is being developed to gain a deep understanding of the process. On the microscale, particle dynamics simulations are conducted using Computational Fluid Dynamics (CFD) and the Discrete Element Method (DEM). The data obtained are used to calculate the growth processes through desublimation on the macroscale. Experimental investigations analyze particle formation processes using SMPS measurements and a further developed 3D light scattering sensor (3DLSS), which are then compared with the simulation.
