2. Main experimental/computational facilities Laboratory of Plasma Processing develops novel plasma generators up to 200 kW of capacity, working at atmospheric pressure and improves the construction of the existing ones. Recently a novel water vapour plasma generator has been developed. The obtained results show that the generator is suitable for the realization of various processes in the reactive arc zone and may be used for the conversion of solid, liquid, organic and inorganic materials into gas. Plasma diagnostics is available by numerical and experimental methods. A numerical research of heated gas jet in the channel was performed applying hydrodynamics software ANSYSFluent. Recently, contact and non-contact methods have been widely applied for plasma diagnostics in the Laboratory. They are: optical spectroscopy method (wavelength range of 250–800 nm); System of double Langmuir probe; Calorimetric probe; Various thermocouples; High speed video camera; FTIR spectroscopy; BET surface analysis; chromatography. • Main research collaborations and industrial partners • Together Laboratory of Combustion processes new long-term R&D programme:”Experimental and numerical research of combustion and plasma processes for improvement of energy generation technologies from renewable biofuel and reduction of environment pollution”. • Scientific work, funded from budget assets:”Synthesis of carbon coatings in argon-acetylene and argon-hydrogen-acetylene plasma and investigation of their properties”. • COST CM0903 activity Utilisation of Biomass for Sustainable Fuels and Chemicals (UBIOCHEM). • International project Research on formation regularities and properties of multifunctional metal oxide coatings formed by combined laser-plasma methods carried out under the Lithuanian- Belorussian bilateral cooperation programme. • Main publications • Grigaitienė V., Snapkauskienė V., Valatkevičius P., Tamošiūnas A., Valinčius V.
