Abstract: A two-dimensional nonstationary model of calculation of heat transfer at viscous fluid droplet spreading over the heated substrate is presented. A process of the fixed droplet spreading over a simple geometry substrate has been calculated. A hydrodynamic picture of the process of spreading has been obtained. The influence of the parameters of the model on the nature of spreading has been studied. The temperature profiles at the droplet surface have been obtained. The setting time of the stationary mode has been evaluated.

Abstract: Numerical simulation of the motion of a viscous incompressible nonisothermal liquid in an open rectangular cavity with a glance of heterogeneity phase characteristics is performed. The hydrodynamic pattern of moving liquid has been obtained. Temperature profiles for solid and liquid phases have been received. The model parameters influence on the motion of the heat carrier and the distribution of temperatures in two phases have been studied.

Abstract: A modified method of small-angle scattering that consists in solving a series of direct problems in aerosol optics is proposed to obtain a function of particle size distibution; a modified method of spectral transperancy is employed to determine the concentration of particles in a cloud. A measurement system comprising radiator (helium-neon laser), photodetector and recording instruments has been developed. Measurements in aerosol clouds are performed.
