Plasmodynamics Of Disperse Systems Laboratory

Basic Research Activities

  • Interphase energy and mass transfer in dust-laden plasma flows.
  • Superfast quenching of melted microdroplet impacting on the substrate.
  • Methods of diagnostics of dusted plasma flows.
  • New generation of plasma equipment for powder coatings deposition.
  • Technologies of plasma spraying of powder coatings (wear-resistant, hydroabrasive-resistant, cavitation-resistant, thermal barrier, catalytic, biomedical, etc.).
  • Computer design and optimization of plasma spray technology.

The Main Results Of Investigations: equilibrium solidification of melted microdroplets impacting on the substrate.

    Theory and modeling experiment.

  • A new theory has been developed and a series of modeling experi- ments has been performed on 'melted metallic droplet - substrate' interaction under complete control of key physical parameters: velocity, temperature and size of particles; temperature of polished substrate. A criterial generalization of data that characterize the thickness of particles solidified on the substrate was performed.

    New method of disperse component diagnostics in dusty plasma jets.

  • A new laser-optical diagnostic method that allows simultaneous in-situ measurement of the vector of velocity, temperature and size of a single particle in heterogeneous plasma jets with a record- beating accuracy and speed of response has been developed.
