	Heat/mass transfer of axi-symmetric, actively controlled impinging jet Trávníček, Zdeněk ; Peszynski, K. Annular nozzle has been equipped by a fluidic control of a jet flow state. The jet flow can be either focused along the nozzle axis or spread out of nozzle axis. Nozzle geometry aimed an enhancement of head and mass transfer on exposed wall by means of active flow control. A visualization of the jet flow was performed, mass transfer was measured by naphthalene sublimation method, and heat/ mass transfer analogy was used. Detailed record
	Fluid dynamics 2001 Jonáš, Pavel ; Uruba, Václav The proceedings contain 32 texts of the contributions from the conference from the fields Fluid dynamics. Detailed record
	Comment of the application of the intermittency factor measurement to increase the accuracy of hte determination of the boundary layer transition start Jonáš, Pavel ; Mazur, Oton ; Stepien, M. ; Uruba, Václav A method of the direct assessment of the intermittency factor distribution inside a transitional boundary layer under outer stream turbulence was developed and proved. It was justified that the Narasimha approximation is not accurate at such boundary itions as the basic assumption that the boundary layer upstream the start of transition is not turbulent, is not valid. The proposed modification of Narasimha formulae seems to be more accurate. Detailed record
	Laminar and turbulent transition in fine-grained non-Newtonian slurries Vlasák, Pavel ; Chára, Zdeněk The transition from laminar to turbulent flow regime is very important for design and operation of non-Newtonian slurries pipelining. The paper deals with experimental investigation of laminar/turbulent transition, flow behaviour and rheological parameters of fine grained highly concentrated non-Newtonian slurries in horizontal pipes. Research is focussed on different character of slurry behaviour in laminar and turbulent region and verification of prediction turbulent model. Detailed record
	Survey of some results on Leray's self-similar Solutions to the Navier-Stokes equations Skalák, Zdeněk The survey of some recent results on self-similar solutions to the Navier-Stokes equations is presented. The question is raised concerning the existence of flow-up via non-stationary solutions of the Leray's equations. Detailed record
