	Study of Anode Attachment Behavior and Its Influence on Plasma Jet in Water-Argon Plasma Torch Chumak, Oleksiy ; Hrabovský, Milan ; Kopecký, Vladimír ; Konrád, Miloš In this paper behavior of anode attachment and its effect on plasma jet in dc water-argon plasma torch was studied.Dependence of plasma jet deflection on argon flow rate and on arc current was investigated.Effect of arc current and plasma gas flow rate on position of anode attachment and on arc voltage fluctuations were studied and processes that control the position was discussed.

	Spectroscopic and Enthalpy probe Diagnostics of Fluctuating H2O-Ar Thermal Plasma Jet Sember, Viktor ; Kavka, Tetyana ; Kopecký, Vladimír ; Hrabovský, Milan Time averaged OES and EP measurements of the temperature and mole fraction of entrained air in the H2O-Ar dc arc thermal plasma jet are compared.It is shown that choosing an appropriate method of evaluation of spectroscopic data may reduce the effects of fluctuations and departures from equilibrium and lead to more realistic results.The differences between OES and EP measurements.

	Condensed Polyphosphate Pigments Prepared in WSP 500 plasmochemical reactor Brožek, Vlastimil ; Hrabovský, Milan ; Kopecký, Vladimír ; Trojan, M. The polyphosphate pigments were produced in a high enthalpy oxygen-hydrogen plasma jet generated in water stabilized plasma torch. Úplný záznam
	Behaviour of Powder Particles in Thermal Plasma Generated by Hybrid Water-Argon Torch Chumak, Oleksiy ; Kopecký, Vladimír ; Hrabovský, Milan The velocity and trajectories of particles injected into thermal plasma jet were measured for hybrid argon/water plasma torch. Effect of argon flow rate on distribution of particle velocities was investigated. Two-dimensional model of particle motion in plasma jet was formulated and computation results were compared with measurements. Úplný záznam
	Investigation of Heat and Mass Fluxes in Thermal Plasma Jet Generated in Water and Water-Argon Plasma Torches Kavka, Tetyana ; Gregor, Jan ; Sember, Viktor ; Hrabovský, Milan Two types of thermal plasma generator with water and gas-water stabilization of electric arc were investigated. Profiles of plasma temperature and velocity in generated plasma jets were determined by enthalpy probe diagnostics.Mass, momentum and enthalpy fluxes in the jet were determined from the measurements for both plasma torches.

	Instability in thermal plasma jet generated by water plasma torch Hrabovský, Milan ; Konrád, Miloš ; Kopecký, Vladimír ; Macura, Pavel Fluctuations and flow instabilities in thermal plasma jet generated in dc arc plasma torch were investigated by optical system with fast response photodiodes. The coherent oscillations were revealed that are produced due to hydrodynamic instability of plasma flow close to the exit nozzle of the torch.Properties of the these oscillations are investigated.

	Desing and modification of water-stabilized plasma generator and multiphase modelling of flow in the arc chamber Hrabovský, Milan ; Matas, R. ; Moravec, J. Two-phase water-air flow in arc chamber of water stabilized plasma generator is modeled using computer code FLUENT. Effect of arc chamber geometry on properties and stability of water vortex is investigated on the basis of the computations. Úplný záznam
	Thermal plasma jets generated in liquid-stabilized and hybrid dc arc torches Hrabovský, Milan This paper presents survey of plasma jet parameters of liquid and hybrid arc torches and discusses physical mechanism that control plasma properties. Special attention is devoted to properties of jets that are important for performance characteristics in plasma spraying. Úplný záznam
