ultiphase flow physics is essential in large
variety of practical applications: e.g. aircraft
icing, erosion and ablation in dusty atmospheres,
combustion, medicine and space problems. Despite
numerousexperimental andnumerical investigations,
some physical peculiarities of supercooled droplets
crystallization physics understanding as well
as nonspherical particles motion simulation in
nonuniformflowsarenotcomplete.Panoramicoptical
methods couldbe essentially improved inorder to get
more information from wind tunnel experiments.
Mathematical models and numerical algorithms for
calculating the motion of nonspherical ice crystals in
inhomogeneous media have been developed and
compared with corresponding experimental results.
Methods for inverse problems of disperse flows
parameters determination via analysis of panoramic
optical measurements data were developed. Based
on the results of experimental studies, dependencies
of the characteristics of the crystallization of a
supercooled liquid in the problem of icing of aircraft
were obtained. Physical peculiarities were discovered
and experimentally fixed. Methods of molecular
physics were used to estimate supercooled droplets
crystallization features parameters. Computational
algorithms and mathematical models for dispersed
flows interaction with a solid surface control at
the molecular level were developed. Results of
parametrical investigations are obtained as well as
corresponding illustrations.
