A method for the determination of the kinematic viscosity of limited volume aerodispersed systems was developed, based on measuring the time for the aerosol’s flowing out and by applying the Poiseuille’s law. A device was developed based on the method. An optoelectronic circuit connected to a PC was made for automation of the measuring process. The values of the kinematic viscosity of various limited volume aerodispersed systems in the process of their evolution were experimentally measured. An evaluation of the mass and size of the finest fraction of the limited volume aerodispersed systems was made, known as Aitken nuclei. A method for the determination of the mass density of limited volume aerodispersed systems was developed, a modification of the one for the determination of the kinematic viscosity. For the characterization of the evolution of the limited volume aerodispersed systems a function was introduced called spectrum of the state of aerosol system. The alteration of the latter was experimentally determined by the influence of magnetic and electric fields. A comparison was made of the probability distribution of the mean values of the density of liquids (tabular data) and limited volume aerodispersed systems (by the experimentally obtained data). For the latter it was determined that it is very close to the Gaussian distribution. |
