Aerosol research laboratory

The department systematically and at the state-of-the-art level builds up facilities for experimental research into aerosol transport and deposition. It is equipped with up-to-date instrumentation for preparation and experimental research of liquid and solid particles. The research activities conducted currently at the laboratory include elucidation of transport of various type particles as well as assessment of their deposition during inhalation into human airways. The laboratory fundamental component is a test rig for aerosol preparation, its mixing with air and measurement of flow operating parameters.

Other laboratory features include generation of liquid and solid aerosols sizing between 0.1 and 10 μm at concentrations up to 106 cm-3, measurement of particle motion, size, concentration and their morphology. The department know-how of complex biological models production is covered by a patent.

Activities carried out

  • preparation of both liquid and solid spherical, porous and fibrous particles
  • measurement of aerosol size and concentration with various methods
  • particle morphology assessment by optical microscopy
  • research into two-phase mixture air-aerosol flow in either free space or complex models with the use of up-to-date optical methods, option of oscillatory flow generation
  • aerosol deposition measurement in models by means of various methods
