Vliv vnějšího buzení na strukturu toku v axisymetrickém proudu vzduchu: studium impaktního proudění dopadajícího kolmo na stěnu
Cvetinovic, D. ; Tihon, Jaroslav ; Vejražka, Jiří ; Drahoš, Jiří
Subject of present work is submerged, round, unconfined impinging air jet, issuing from a bell-shaped converging nozzle.
Dynamické chování impaktního proudu vzduchu za buzených tokových podmínek
Tihon, Jaroslav ; Bourdette, V. ; Vejražka, Jiří ; Pallares, J. ; Salucna, C.
This paper presents the results of experimental investigation of the velocity field inside a round impinging jet under excited flow conditions.
Vliv tuhé fáze na přechod režimů toku v třífázových probublávaných kolonách
Mena, P. C. ; Rocha, F. A. ; Teixeira, J. A. ; Drahoš, Jiří ; Růžička, Marek
The goal of this work to examine the influnce of solid particles on homogeneous regime stability and regime transition in a three phase bubble column. For that, two studies were done, one focused on the regime transition and the other on visualization of bubble-particle interaction.
Přechod režimů v probublávaných raktorech: Vliv návrhových parametrů a vlastností kapalné fáze
Fialová, Marie ; Drahoš, Jiří
The experimental data show that low viscosity can stabilize the homogeneous bubbling regime whereas moderate viscosities supress formation of homogeneous bubbling regime above a certain critical value of the viscosity. The dependence of critical gas holdup on viscosity of the solution exhibits a maximum at low values of viscosity.
Dynamika solitárních vln při filmovém toku kapalin
Tihon, Jaroslav
The regular solitary waves on the surface of a liquid film flowing down an inclined stationary plate were excited by means of the flow rate pulsations. The results of experimental investigations provided the basic characteristics of surface waves and confirmed the existence of a small backflow region located just in front of the solitary waves.
