TEMPERATURE FIELDS IN A LIQUID DUE TO THE THERMOCAPILLARY MOTION OF BUBBLES AND DROPS
Autor: R. Balasubramaniam, P. H. Hadland, Günter Wozniak, R. S. Subramanian
Publikováno v: Proceeding of Microgravity Fluid Physics & Heat Transfer.
Experiments were performed on the motion of isolated air bubbles and drops of Fluorinert FC-75 moving in a Dow-Corning silicone oil under the action of an applied temperature gradient in a reduced gravity environment aboard the Space Shuttle in orbit

Experimental Investigation of Spray Characteristics of Pre-Filming Air-Blast Atomizers II – Influence of Liquid Properties
Autor: Günter Wozniak, M. Roudini
Publikováno v: Journal of Applied Fluid Mechanics, Vol 13, Iss 2, Pp 679-691 (2020)
One of the most important advantages of twin-fluid atomizers over other atomizers is the opportunity of atomizing liquids in a wide range of liquid properties efficiently. Thus, the fundamentals of spray dynamics, such as spray pattern, liquid breaku

Experiments on the transition of thermocapillary bubble convection towards turbulent flow
Autor: Ebram Tadrous, Günter Wozniak
Publikováno v: Physical Review Fluids. 6
This study reveals that under appropriate conditions a surface tension driven (thermocapillary) flow can become turbulent. Thermocapillary bubble convection undergoes various nonperiodic modes as the Marangoni number (Mg) increases till reaching the

Large Scale Fluctuations in an Axisymmetric Sudden Pipe Expansion with Large Aspect Ratio
Autor: Günter Wozniak, Oliver Sommer, A. Ringleb, W. Schlüter
Publikováno v: Journal of Applied Fluid Mechanics, Vol 11, Iss 4, Pp 877-883 (2018)
The aim of the present work is the investigation of the turbulent flow field downstream of an axisymmetric sudden expansion with a large aspect ratio of D/d = 12,3. For the fundamentally understanding of the flow some numerical results are presented.

Experimental Investigation of Spray Characteristics of Pre-filming Air-blast Atomizers
Autor: M. Roudini, Günter Wozniak
Publikováno v: Journal of Applied Fluid Mechanics, Vol 11, Iss 6, Pp 1455-1469 (2018)
A bulk of a liquid dispersed into single droplets using the kinetic energy of a high-velocity gas in an air-blast atomizer is frequently employed in technical atomization processes. The atomized liquid is primary situated on a surface (prefilming sur
