It was recently shown that an additional non-Brownian motion should exist in all, even uniform, aerosols in presence of heterogeneous reaction. In this experiment, the phenomenon of the desublimation reaction is investigated.
For a small growing crystal suspended in a gas, the overall gas molecule momentum flux should not be equal to zero because of the different growth rates of the crystal faces. It gives rise to the jet motion of the crystal and may be applied for the investigation of the growth mechanism.
Experiment objectives comprise the following:
It is achieved by the analysis of the aerosol particle motion parameters. Inert particles are also introduced into the aerosol to separate the jet motion from possible external disturbances. Weightlessness condition is requested to avoid sedimentation that heavily shields the jet motion on the earth.
